For five years, no trace has been found of two high-school friends who went hiking in the woods near Nashville. The third teen, Amber Ryder, was discovered at the bottom of a ravine with a broken arm, head trauma--and zero memory of the horror that put her there. What started as a cold case has become a fresh hell for forensic technician Georgia Morgan. Another woman's body is found in the woods, and it leads to the missing teens' remains. But while Georgia works with Amber to try and reawaken her memories, her gut tells her the worst is yet to come. Homicide Detective Jake Bishop can't be sure whether Amber is an expert manipulator or the killer's next target. Either way, he's determined to protect Georgia. Because the deeper she digs into the past, the deadlier the secrets that emerge, and a nightmare years in the making is about to come to a bloody, terrifying end.
