When Detective Jason Morgan is tasked with keeping a local restaurant owner safe as part of a make-or-break case, he rises to the challenge. The job is his first priority, and he owes it to the memory of his father, a detective killed in the line of duty, to do it at any cost. But Jason never expected Serenity Gallagher to be so beautiful, so serious...or so tough to protect.

Serenity has moved from place to place at the whim of her capricious mother all her life. The last thing she wants is to leave the diner she finally calls home, even if it means being stuck with a sexy blue-eyed detective. But she’s the only witness to a horrible crime, and the man behind it wants her very, very dead. Going into protective custody means survival, no matter how much Serenity hates hiding.

As Jason and Serenity bide their time together, they are shocked to discover they have much more in common than the surface reveals. But keeping her safe is Jason’s number one priority, no matter how much he’s drawn in by the woman beneath the witness, and Serenity’s past makes it difficult to trust. As the stakes get higher and the spark burns hotter, can Jason and Serenity draw the line?
