Kaitlyn Nichols craves a little mystery and mayhem in her life. Having a secret agent for a father should do the trick, but unfortunately Dad is no 007, and danger is nowhere on the horizon.

But all that changes when Mr. Nichols brings home Blaine, a seventeen-year-old hottie who's about to enter the Witness Protection Program. Suddenly Kaitlyn's in the perilous position of protecting the cutest guy she's ever met!

When Dad enrolls Blaine in her high school, it's up to Kait to detect the girls who want him...and the guys who want him dead. Meanwhile, Kait's about to discover that there's one little thing she can't protect -- her heart.
