Undone by Karin Slaughter

 

A retired couple is driving on a country road when the horrific happens.  A woman bolts from the shoulder and runs right into their car.  Luckily, the car behind them has an EMT as the driver and he is able to provide first aid until an ambulance arrives.  But the woman's injuries are much more than being struck by a car would cause.  She is beaten, starved, cut and burned on every inch of her body.

When she arrives at the hospital, her case is assigned to Sarah Linton.  Sarah has fled to Atlanta after the death of her police chief husband three years before.  Now she works in the ER room and she hasn't seen this kind of damage often.  As she fights to save the patient, police arrive at the crime scene.

Will Trent and his partner, Faith, are assigned to the case.  Will finds a cave that has been dug under the ground and set up as a torture chamber.  They also realize once there that there was another victim and a search is soon on for the other woman.  She is found but did not survive.  Soon other women are kidnapped and taken and everyone knows the same horror is in store for them if they can't be found.  Can Will and Faith find the killer in time?

This is the third novel in the Will Trent series.  In this one, the relationship between Will and Faith grows stronger but interestingly, Will and Sarah are immediately drawn to one another.  The case is intricate and horrible and the reader will find themselves turning pages quickly to find the answers.  This book is recommended for mystery readers.
