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.
