Olivia (Livie) St. Martin's life was changed forever when she witnessed the abduction of her sister. It was her testimony that later convicted the man and sent him to prison for kidnapping and murder. As an adult, Livie is now Director of Trace Evidence and Materials Analysis at the FBI lab in Virginia. Her life is again turned upside down when the man she helped put in prison is released after DNA evidence clears him in the murder of her sister.

Fearful that the real killer is still on the loose and killing little girls, Livie leaves the lab and becomes involved in the investigation of a serial killer in Seattle. Working with Police Detective Zack Travis, she realizes the man they're searching for is the same one who killed her sister, and the race is on to find him before he chooses his next victim.

Ms. Brennan has penned a taut psychological thriller. Olivia and Zack are well-written, driven characters, and the killer is frighteningly evil. If you enjoyed THE HUNT and THE PREY, you will definitely enjoy THE KILL.
