Cold, Cold Bones Part of A Temperance Brennan Novel

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.
