Some women are worth waging wars over.

Lenny Primrose has lived her entire life as her rich father's puppet. Now, at twenty-three, she's no longer interested in playing his games. Unfortunately, the only way to avoid being married off to one of her father's business partners is to involve the man he fears most: the British assassin who almost killed him.

Jonas Wolfe would be content to never be in the same room as a Primrose ever again. His days are filled with contracted murder and running his pub – anything to keep from sitting around thinking about his one failed mission. But when Lenny commits a rash crime, Jonas steps in to help, and extracting himself from her family becomes impossible.

Especially when she bats her pretty green eyes, proposing a fake relationship that she vows will benefit them both. Interested in improving his public image, Jonas agrees, and it isn't long before lingering looks become scorching hot kisses. But even as the two grow closer and bond over their common enemy and undeniable chemistry, Lenny still remains distant and closed off.

Turns out she's keeping a horrible secret…one that threatens to tear apart everything they've built together.
