Announcing You’ll Be The Death of Me

05.25.2026 by Crystal Kaswell // Leave a Comment

A thrilling cat and mouse romance. Coming Fall 2026.

Please note: text has not yet been edited

Jamie

Agent Matteo Locke slaps one handcuff on my wrist. The other goes around his.

“You’re not going anywhere this time, Moriarty,” he says in that smooth British-Italian accent of his.

I look up at him with all the innocence I can muster. “Is this really necessary?” I bat my lashes. I tilt my head just enough my blonde strands catch the sun.

His dark eyes go to pale pink robe barely covering my soft curves.

His breath catches in his throat. His cheeks flush with desire.

He swallows hard, finding his poker face. His I’m all business. I don’t care how much I want you tone. “Was stealing $200 million in art necessary?”

Three hundred million, but who’s counting?

“I can’t help myself.” I stare into his gorgeous eyes. I reach out with my free hand and run my fingers over his strong jawline. “I love Van Gogh.”

He leans into my touch for a second, then he’s back to the Mi6 Agent who doesn’t take shit. “If you play nice, I’ll talk to the warden. Get a print for your wall.”

He’s so fucking sexy here. In control and completely at my mercy at the same time.

“I’d rather look at you.” I make my voice soft and breathy as I run my fingertips over his chin.

He lets out a single sigh of need and he snaps back to the man he’s supposed to be. “I’ll send a photo,” he says, his voice ice and steel.

Which only makes me hotter. My core tightens. My chest flushes. I want him so badly. I always do.

“Will the picture keep me warm at night?” I ask in my best femme fatale voice. The one I only use for him. Devious, yes, but powerless to resist him too.

“I know I’m gorgeous, but I’m not the sun, mi diavolessa.” He calls me by his favorite pet name. His little devil. “I can’t warm that cold-blood of yours.”

That’s a good one. He’s getting better at this banter thing.

And he’s wrong—

He is the sun. He’s radiant.

But enough foreplay. Let’s get into this.

I trace a line down his chin, neck, collarbones.

His lips part with a groan as I undo the top button of his shirt.

“If we’re going to be stuck together, we might as well enjoy the hour until your backup arrives,” I say.

He looks down at me with heavy eyes as he brings his hand to my neck.

His touch is soft. Tender.

Not what I expect in this situation. And all the better for it.

For a moment, I savor the warmth of his hand on my skin. Then I shift into the seductress I invented just for this.

I drop to my knees and distract him thoroughly while I swipe the keys from his pocket.

He’s cuffed to the bed before he has any idea what’s happening.

I push him onto the soft surface.

He lands with perfect posture, poised and ready for anything.

Matteo looks up at me with that mix of vulnerability and confidence only he can offer. He’s starting to lose the character. And he doesn’t have another one, not really.

Only the loving boyfriend he really is.

“Now, I have you where I want you,” I say, as I slide out of my pastel pink robe. Then it’s the matching bra and panty set that blends into my skin, makes me look sweet and innocent.

He watches, helpless. Rapt.

I slide into his lap.

His eyes go wide for that perfect moment of union.

Then it’s a buzz against my thigh. His work phone.

“Jamie, baby. I’m sorry. I have to check that,” he says, pausing the scene officially.

Damn. I thought we’d finally get to the next phase of this roleplay. Where he distracts me, steals the keys back, and ties me to the bed.

But, no, it’s always work first.

I swallow the frustration that rises in my throat. He doesn’t want to see that. They never do.

I slide off so I can reach his phone. My body whines from the loss of heat, but I focus on action as I hold the phone to his ear.

He’s all business as he speaks with his boss. Yes, no, when, where.

The call ends.

I consider leaving him tied up here. It would be apropos. And it would make my task easier.

But that’s not how I want this to go. There’s just something about Matteo. I want to protect him.

“How long do you have?” I ask, in the sweetest voice imaginable. This is my last chance to play devoted girlfriend. I have to make it count.

“Not long enough to do this properly,” he says, regret in his voice, “but I won’t leave you wanting either.”

My heart thuds against my chest. My stomach fills with butterflies.

For a second, I reconsider.

I’m going to miss him. Miss this.

But what other choice do I have? Even if I wanted to quit my job—and I don’t—I can’t. There are strict rules around retirement.

So I focus on this moment. This last time that he’s mine as I uncuff him and surrender to the feeling of his head between my legs.

And then I kiss him like it’s the last time.

Unless the stars align, it is.

He releases me with a sigh—one that says, I don’t want to leave so quickly, but I know you’ll be here when I get back. Then he stands and washes up and I do what I need to do.

I get the address from his phone. I slide into my clothes. I walk him to the door.

I steal one more sweet, soft, slow, soul-filling kiss.

He looks down at me, curiosity in his dark eyes. He can tell I’m off someplace. He can tell the energy is different.

I rise to my tiptoes and wrap my arms around him and hold him tightly. “In case you don’t make it back,” I say.

He nods into my shoulder, accepting my answer but not buying it.

And then he leaves. What else can he do? He doesn’t have time to stop and break it down.

He has a witness to interview.

Hopefully, he’s distracted by this glimpse of the truth.

He sees me.

That’s why he calls me his little devil.

He just can’t see the one tiny thing I keep hidden:

I kill people for a living.

*

Matteo

The safe house is a quiet spot. A villa nestled on a cliff, surrounded by low brush and the brilliant orange light of sunset.

There’s a low likelihood of danger—only Jamie, my boss, and the witness know I’m in this little town outside of Nice—but I still need to bring my A-game.

If I don’t flip Cassanova, I hit another dead end. It might be another two years of chasing Olympus before I find one this good. And I need to stop them.

The female-run crime ring sells assassinations and information to the highest bidder. They’ve racked up quite the body count and we haven’t come close to stopping them.

This man knows Nike, the assassin who is constantly one step ahead of me.

But not today.

Today, I get a name

The pent-up desire from earlier threatens to steal my concentration. I love the occasional abrupt end, so to speak. It makes the eventual climax that much better.

I allow myself one moment to savor the memory of Jamie’s groan in my ear, then I check the dirt road for a tail, and I slip into the abandoned mansion.

Inside, the villa is gorgeous but unkempt. Dust covers old furniture. Musty blinds block the brilliant sunset, but they can’t keep the scent of salt and citronella from the air.

I creep up the winding wooden stairs.

But I’m too late.

Casanova is in the master bedroom, handcuffed to a chair, plastic bag over his head, body limp.

He’s turned to the messy four-poster bed like he’s ready to watch the action on the faded pink sheets.

Only there’s no action. The room is silent. No breath. No footsteps. No wire trap.

There’s no one here. No one alive.

His lack of a pulse confirms it. He’s still warm. He hasn’t been dead long.

Wait a minute.

Those handcuffs are familiar. The pink color. The furry texture.

The ones Jamie brought the first time she suggested a cop-criminal role play scenario.

But how could she—

How could anyone beat me here?

Then I see it, tucked into his pocket.

The card that came with the flowers I sent her on Valentine’s Day, along with a perfectly pressed rose petal.

My message on one side.

Ti amo, mi diavolessa.

Then the other, in her handwriting.

Sorry, baby XO.

It hits me all at once.

Nike—the assassin I’ve been chasing the last two years—

Is my ex-girlfriend.

Sinful Serenade Covers

03.13.2023 by Crystal Kaswell // 4 Comments

Sinful Serenade is my favorite series, now and forever. It’s the first thing I wrote that I loved that other people loved too. I filled Sing Your Heart Out with all my high school musician crush feelings… the ones I still have (though not as strongly, if I’m being totally honest… it’s been eight years and I’ve matured and moved on to some degree, and that particularly lyricist is just sorta a has been now. Sorry! That one album is still my favorite though.)

(Editor’s note: Crystal’s Spotify play history does not align with the claim she has moved on).

Over eight years, the Sinful Serenade series has had a bunch of different covers! It’s been so much fun presenting the series in new ways. And here they are.

First, a note about covers: I’m a reader first. As a reader, I love a beautiful, unique cover. I prefer something unusual to something typical. As an author, I’m both an artist and a publisher. My artistic side wants a beautiful, special cover, because my books are beautiful and special! But my publisher side knows I need to reel it in: the cover can be beautiful and special… if it also signals the right things. Covers are “signals” and they need to contain A LOT of information: the genre of the book (romance), as well as the subgenre (in this case, new adult and rock star), the heat level (scorching), and the tone (a mix of humor and emotion). There’s a lot of other stuff I want to signal, but some of it is just hard to say visually!

As a reader, I totally get the hatred of a new cover… how dare an author change from the cover I loved! But as an author, I know it’s a necessary part of the job (an evil if you see it that way, or a fun experiment if you see it that way… and I do. I love trying new things!) Because I need to give the series a fresh look from time to time, in order to bring in new readers, so I can keep writing books. (and have a chance at returning to the world… because if no one wants to read a series anymore, there’s no reason to write a spin-off or a next gen or anything similar).

The Original Covers:

Sing Your Heart Out Original Cover
Strum Your Heart Out Original Cover
Rock Your Heart Out Original Cover
Play Your Heart Out Original Cover, with pink and greyscale design and bass guitar
Sinful Ever After Original Cover

Way back when, in 2015, I had very little idea what made a cover sell. But I had a few things to go on: sexy couples and musical instruments. I tried to hire a designer for a sexy couple and she made a nice cover, but it just didn’t say rock star, or feel exciting. So I searched far and wide, looking at “premade covers” everywhere. (A premade is a cover a designer has already created, which an author can buy, and make minor changes too–title & name of course, and sometimes some colors and fonts. The “typical” cover process is a custom cover, where an author brings a prompt to a designer, and she crafts a beautiful cover based on the author’s instructions. It’s a collaborative process, where, ideally, the designer brings a great mix of creativity and market knowledge, so the author has a cover they love that also tells readers “this is the kind of book you like”).

These are my favorite covers! I absolutely love them. The greyscale, the musical instruments, the fun pink font! Amazing! At one point, I did change these covers… I asked my designer to make my name bigger, so I looked like a bigger deal. (Later, I switched my name to my new branding, the one on my Inked Hearts Covers). For a long time, these covers did really well. But the look started to fade… between the fonts, the gritty texture, and the greyscale, these started to say 2016 in a bad way. And this sort of cover started to appear more and more on books featuring “alphaholes” and “bullies” and general “dark romance” sorta vibes. The covers no longer said FUN AND PLAYFUL because so many other books with similar covers said MEAN DUDES ONLY. And since I can only control myself, not other authors, I decided to change my covers.

The Second Try:

These were by Sarah Hansen at Okay Creations, the designer who created my Inked Hearts covers. I asked her to create some covers that looked a little more modern, covers that would signal “these books are just like the Inked Hearts books you love so much.” We struggled with the color scheme–the initial look she tried was way too pastel–but the final covers turned out great. They sold well to Inked Hearts fans and a lot of new readers fell in love with Miles, Drew, Tom, and Pete all over again.

Take Three: The Guys

A long, long time ago, I decided to write an alt POV version of Sing Your Heart Out, mostly from Miles’s POV. This book, called Just a Taste, did not sell particularly well. A lot of Sinful fans loved it but that was about it. Oh well! So it goes with our author experiments. I had a lot of fun writing the book. In hindsight, I would have written the entire thing from Miles’s POV, replaced less scenes, added more new ones. But I love the book as it is. (At the time, I felt Meg’s POV was necessary for context in a few scenes). I wanted to try a totally different look for this cover, one that said “dive into the head of this damaged dude” rather than “rock star” or even “schmexy couple” so I tried a style of cover that rarely works for me… a solo guy.

I know, I know… so many readers love sexy dudes, but, for some reason, I just don’t know what it is they love. I pick the wrong guy or the wrong image. These covers just don’t usually do well for me. They don’t speak to me and maybe that’s why. I hate to admit this to you, but I find images of men sorta boring.

With this new book, I retitled my Sinful Serenade prequel, Sing for Me, to call it Just a Tease.

Just a Tease Prequel
Just a Taste

This cover did all right and readers enjoyed it. I loved the model’s brooding look and suggestive pose. And when I started working with a new ad person, she loved it too. She convinced me to recover the book with this concept, but I never really *loved* the look. They did okay with Facebook ads, but it turned out they were too sexy for AMS (Amazon’s internal ads). AMS really hates horizontal images.

I tried a few things with these and they did okay, but never well enough to justify spending more money on ads. Plus, they didn’t really match up with the Dangerous Noise covers. So, eventually, I switched back to the pervious covers.

Sinful Serenade Man Covers

The Illustrated Edition

My Inked Hearts spin-off series Inked Love never really took off. It did okay. I tried all sorts of covers. Men (but the were horizontal… since that was the concept, and that meant ad troubles). Couples that matched Inked Hearts. Ladies. The ladies performed the best but they still didn’t knock it out of the park. So, on a whim, I tried illustrated covers and I LOVED them. They did really well with AMS (and the new kid on the scene… TikTok) and I thought they were so much fun. So I tried them for Sinful Serenade. To be honest, I wanted to do something more typography/object based, but it just wasn’t happening with my designer, so we ended up with these really cute figures.

To be honest, again… I have been expecting negative reviews on these books. The covers are cute. I get that they say cute (and I get if some people find them twee). But so far, I’ve had really positive feedback. Even though these books are angsty and smutty as hell.

I don’t expect to keep these up forever, but for now, I love them. Along with the change in covers, I updated the new paperbacks so the vectors better reflect the heroine’s journey (rather than the hero’s instrument). It’s something that’s important to me after so much time in romance: I always want my heroines and their journey to take center stage. (Or at least get equal weight).

Playboy Prince Cover Reveal

11.18.2021 by Crystal Kaswell // Leave a Comment

Playboy Prince is coming Dec 2nd
Pre-Order Now

Playboy Prince cover featuring pink bow-tie with engagement ring & pink petals

My playboy boss wants me to slip into a new position:
Fake fiancée.

Coming Dec 2

Pre-order now at a special pre-order price

I had sooooo much fun writing this book! Liam Pierce is pure troublemaking bad boy. Rebellious, funny, guarded, obsessed with the heroine (his employee slash best friend slash fake fiancée) in a way he can’t begin to see.

And his heroine Briar is smart, tough, determined, caring, and completely willing to call him on his shit at every opportunity.

This is all my favorite tropes (friends to loves! fake relationship!) plus one I don’t normally read or write (boss / employee… I’ve never worked in a “normal” office and I don’t typically find these books relatable, but the setting just worked for these two).

(You can read Broken Beast now on Amazon, available with Kindle Unlimited. eBook and paperback available. Audio coming soon).

Love,

Crystal
