A brooding ex-Marine out for revenge and an undercover agent with everything to lose become entangled in a dangerous game—where trust is deadly and attraction could cost everything.

When undercover FBI agent Lexi York shows up at Gunner Steele's doorstep demanding protection, he knows two things: she doesn't trust him—and he doesn't care. Not until she reveals she holds the one thing he's been chasing for years: information about the man who destroyed his family.

Smart, intriguing, and maddeningly irresistible, Lexi is everything Gunner doesn't need—and the only woman who's ever made him hesitate.

But as the walls close in and blood ties begin to unravel, Gunner faces an impossible choice: avenge his family . . .

Or protect the one woman who just might be his future.
