Unforgivable

Mia Voss, a DNA tracer for the Delphi Center, a prestigious private forensics laboratory, is endangered at every turn of Griffin's high-octane third Tracers novel (after July 2010's Unspeakable). After Mia narrowly survives a carjacking, her nephew's life is threatened, and several attempts are made on her life. Detective Ric Santos is investigating a few brutal sexual homicides and is determined to protect Mia at any cost. When Mia discovers a link between Ric's current cases and a cold case from six years before, it jeopardizes her life and her career and strains their already tenuous romantic relationship. The science is fascinating, the sex is sizzling, and the story is top-notch, making this clever, breakneck tale hard to put down. (Dec.)
