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.
