The debut psychological-horror novel from author Marty Thornley is a page-turning ride, a front row seat to a clinical trial gone horribly wrong. For Greg Owens, this was supposed to be a chance to end years of back pain and escape his reliance on pain pills. If it all worked out, he could maybe even get back the life he left behind as the pills took control. Instead, as the patients are cured of their physical pain, they encounter a different sort of pain building inside them - obsessive thoughts, depression, self-destruction. The side-effects grow worse, and the suspense ratchets tighter. The patients want answers and violent revenge, setting them on a collision course with a crazed doctor, determined to protect his life's obsession.
