Predatory Game — Christine Feehan

Feehan returns to the world inhabited by GhostWalkers, men and women invisible to their enemies, yet unprotected from their own haunted pasts--and from the passions that could be their downfall...

Saber Wynter is running from her past when she meets Jess Calhoun, an ex -- Navy SEAL who is physically and emotionally compromised by his own mysterious and violent history as a GhostWalker. What Jess senses in Saber is a kindred spirit, a lost soul desperate for sanctuary. He offers her a home, a job, and a haven where she can safely reveal the secrets that shadow her. But danger follows her, too. Now, the riddles of both their pasts are about to collide, shattering the promise of their future with the ultimate betrayal.
