Lane Cooley is the best Homicide Detective on the LAPD. But she isn't anything like you'd imagine. She's no fast-talking femme fatale... no, she's a Good Mormon Girl who doesn't smoke, drink, cuss, or even watch R-rated movies.

But that doesn't mean Lane misses out on all the blood and guts. Especially now. A new serial killer is in town, one who knows all the cops' tricks, all their secrets. One who is targeting young girls, killing them, and cutting them to pieces.

Now, Lane has to race against the clock to find the killer. Because the murderer has chosen his next victim. And it's Lane's little sister.
