Reichs, Kathy. Temperance Brennan series.

Title from web page

Winter has come to North Carolina and temporarily idle forensic anthropologist Tempe Brennan is content to dote on her daughter Katy. But when mother and daughter meet at Tempe's place one night for dinner, they find a box on the back porch. Inside: a very fresh human eyeball. GPS coordinates etched into the eyeball lead to a Benedictine Monastery where an equally macabre discovery awaits. Soon after, Tempe examines a mummified corpse in a state park, and her anxiety deepens. There seems to be no pattern to these random killings, except that each mimics in some way a killing that a younger Tempe witnessed, analyzed, or barely escaped. Who or what is targeting her, and why? Helping Tempe discover the answers is detective Erskine "Skinny" Slidell, retired but still volunteering with the CMPD cold case unit. As the two penetrate a bizarre survivalist's lair, even Skinny's mood darkens. And then Tempe's daughter Katy disappears
