KATHY REICHS - Cold, Cold Bones

In a profession like this, you're bound to make enemies . . .

An eye . . .
 
It all starts when Dr Temperance Brennan finds a box on her porch. Inside is a fresh human eyeball with GPS coordinates etched into it. They lead her to a macabre discovery in a Benedictine Monastery, and soon after she discovers a mummified corpse in a state park.
 
. . . for an eye
 
There seems to be no pattern to these killings, except that each mimics a killing connected to something a younger Tempe experienced, or barely escaped. Someone is targeting her, and she needs to figure out why before they strike again.
 
And then her daughter Katy disappears.
 
Someone is playing a dangerous game with Tempe.
And they won’t stop until they have taken everything from her . . .

Electrifying, heart-stopping and compulsive, this is Tempe’s most personal and dangerous case yet . . .
