Camryn Lane is living her dream. After years of struggle and rejection, her first novel has finally been published. Her editor is happy; her teenage daughter is proud; and her boyfriend and friends are all excited for her. She’s on top of the world—until she receives a disturbing message from an unknown sender.
 
Rattled by the accusations she finds there, Camryn swallows the sick feeling in her stomach and resolves to put the missive out of her mind. But when she checks her ratings on a popular book site, she finds a scathing one-star review. The reviewer is so articulate and convincing that soon, Camryn’s book is flooded with bad reviews. Could the reviewer be the same person who sent the ugly email? And why do they want to ruin her?
As the online harassment creeps into Camryn’s personal life, she vows to find out who’s behind it. Is it really a disgruntled reader? Or could it be someone she knows? The troll’s actions are escalating, and when the abuse turns deadly, it will take everything Camryn has to unmask the enemy so intent on destroying her—and finally learn why she's being targeted.
