My Best Friend's Billionaire Brother

He’s off-limits. Untouchable. And one weekend away from breaking every rule.

Josie Donavan has spent years trying to forget the one man she was never allowed to want—her best friend’s older brother. William Summers is rich, brooding, infuriatingly hot… and way out of reach. But when they’re forced to share a luxury villa for a weekend wedding in Cabo, all her buried fantasies come rushing back.

He’s grumpier than ever.
She’s sunnier than he remembers.
And the tension between them? About to boil over.

Will Summers doesn’t do relationships. As heir to one of Boston’s most powerful families, he’s always kept things simple: short-term, no strings, no mess. But Josie isn’t just any woman—she’s the one who got away. The one he never should’ve wanted. Now grown up, gorgeous, and very much spoken for, she’s still off-limits… but suddenly impossible to ignore.
He can’t stand the thought of her with another man.

He’ll protect her. Claim her. Ruin her for anyone else.
There’s only one problem: falling for her might destroy everything.

A sizzling romance, and the fourth standalone installment of The Billionaire Brothers Series, this book is as hot as they come.
