A first-year medical student determined to do everything right . . . discovers something very wrong. Now somebody wants her dead.

Tanna Christensen spent countless hours planning for her first gross anatomy dissection, but nothing could have prepared her for what she's found. Beneath her scalpel lies a cadaver riddled with disturbing genetic abnormalities-evidence pointing to an unthinkable crime.

Tanna believes her discovery is the tip of a terrifying secret that goes far deeper than a single corpse. But when her investigation leads to a brutal murder, a lethal cover-up threatens to destroy the future she once dreamed of.

And now she's the next target.

Afraid and on the run, Tanna must expose the truth before more lives are lost-including her own. Or is it already too late?
