Mask of a Hunter - The Seekers, #2

He's street smart. She's book smart.  They must learn to trust each other. Or die. Undercover Seeker Ace Lyons is the man least likely to mix business with pleasure. But the reckless behavior of the fiery librarian he's sworn to protect is threatening to ruin his investigation. Pretending to be her lover is the only way to keep them both safe. Rory Cates didn't count on the dark and unpredictable Seeker dragging her into his arms.
The passionate kisses meant for show in front of the biker gang soon shake them to the core. When his cover is blown, it puts Rory right in the line of fire .
