A romance trilogy

The Wilder Brothers

Three brothers. Three empires. Three women who refuse to be conquered. Spicy, swoony, and full of brooding billionaires who finally meet their match — set in the boardrooms, penthouses, and stolen moments of New York City.

Book One

The Billionaire's Redemption

She hates him. He deserves it. But redemption sure does look good in a tailored suit.

the story

My new boss? Hot. Heartbreaking. And hell-bent on making me his.

Ethan Wilder. My brother’s ex-best friend. My ex-crush. My current problem in an expensive suit.

Five years ago he seduced me to steal my brother’s company secrets. (He failed, for the record.) And now, thanks to a contract straight from hell — and my mother’s charming debts — I’m stuck working for him for three soul-crushing years.

And Ethan? He’s made it his new mission to win me over. With looks that melt me on the spot. With words that blur every line. And with an obsession that’s got ‘HR complaint’ written all over it.

I told myself I wouldn’t fall for him again. I told myself I wouldn’t end up in his bed. Spoiler: I did. And when I tried to walk away? Well… let’s just say the stick turned pink.

Ethan Wilder never loses. And this time, he wants it all — me, the baby, and maybe a wedding band while he’s at it.

What readers have to say

★★★★★

I devoured this in one night. Ethan Wilder is the kind of book boyfriend who ruins you for fictional men everywhere — and Natalie absolutely held her own. The chemistry crackled from page one.

Goodreads review

★★★★★

Workplace romance done right. The slow burn turned into a wildfire and I was here for every second. The age-gap tension was *chef’s kiss*.

★★★★★

KJ Raffat writes the most deliciously tortured heroes. The ‘stick turned pink’ scene had me screaming into my pillow. I need book two yesterday.

Book Two

The Billionaire's Rival

Office enemies. Bedroom frenemies. Now she's the only one he wants.

the story

He stole my promotion. I’ll steal his sanity.

Caleb Wilder has been my rival since college. He beat me out for valedictorian. He stole the internship I’d been working toward since freshman year. And now — surprise — he’s the new VP at my firm, the one I just got passed over for.

I should hate him. I do hate him.

But hate doesn’t quite explain why my hands shake when he walks past my desk. Why I can’t stop watching the way his jaw tightens when I push back in meetings. Why I let him pin me against my office door at the holiday party and I didn’t say no.

We have rules now. No feelings. No questions. No telling anyone. Just two enemies blowing off steam in expensive hotels and locked conference rooms.

Until he starts saying things he shouldn’t. Looking at me like he means them. And I start wondering if maybe — just maybe — we’ve been playing the wrong game for the last seven years.

ENEMIES TO LOVERS DONE PERFECTLY. Eve is the kind of heroine I want to be friends with — sharp, ambitious, doesn’t put up with Caleb’s nonsense. Until she does. And it’s GLORIOUS.

The conference-room scene? Excuse me while I go reread it for the fifth time. KJ writes tension better than anyone in the indie space right now.

Caleb Wilder is officially my favourite bookish bastard. The way he loved her quietly for seven years had me sobbing. Hand me book three immediately.

Book Three · Pre-order

The Billionaire's Runaway

She left him at the altar. Now he's the only one who can keep her safe — and the last man on earth she should trust with her heart.

Pre-order — releases June 2026

the story

I ran from the wedding. I should have run from him years ago.

Sebastian Wilder was supposed to be my way out. Marrying the youngest Wilder brother was the plan my father drew up before he died — a merger of two families, two empires. I agreed because I had no other choice.

Until I did.

I left him at the altar wearing a borrowed dress and riding a stolen motorcycle. I thought I was free.

I was wrong.

Because someone wants me dead. Someone with my father’s signature on the contract that promised me to Sebastian. And the one person who can protect me — the one person whose name on a marriage certificate would make me untouchable — is the same man I publicly humiliated in front of three hundred guests.

Sebastian Wilder doesn’t forgive. He doesn’t forget. But he might just save me. If I’m willing to walk back down that aisle.

What readers have to say

★★★★★

ARC reviewer here — Sebastian Wilder might be KJ’s most devastating hero yet. Quiet, controlled, and absolutely undone by Iris. I screamed at my Kindle multiple times.

— Maya I.

Early ARC reviewer

★★★★★

If you’ve been waiting for the youngest Wilder brother’s story — it was worth every second. The marriage of convenience trope has never been better.

★★★★★

I read this in one sitting at 2am and I have regrets only because I now have to wait for everyone else to read it so I can scream about it with them.
