Double Cross
When a pharmaceutical exec needs protection, he hires former Secret Service agent Will Shannon. But the night Will wakes up with a massive headache and a dead client in the next room, he knows something's gone terribly wrong -- and he's about to take the fall.

Double Back
There's only one person he can trust: Caitlyn Monroe. His former partner -- and lover -- she hasn't seen him in years, but she can't leave him at the mercy of the FBI . . . or the killers who are still after him.

Double Blind
Now the two of them are on the run, desperate to discover what Will's client knew, and why he had to die for it. And while they can't see a way out, the sparks that still flare between the couple are perfectly clear.
