"Camryn Hart is living her dream. After years of struggle and rejection, her first novel has finally been published. Her editor is happy; her fiance, Matt, is supportive; and her friends are all excited for her. She's on top of the world -- until she receives a disturbing email from an unfamiliar address. Rattled by the accusations she finds there, Camryn swallows the sick feeling in her stomach and resolves to put the email out of her mind. But then she checks her ratings on a popular book site and finds a similarly scathing one-star review. The reviewer is articulate, passionate, and convincing, so much so that other reviewers start to fall in line. Soon, Camryn's book is flooded with bad reviews. Could the reviewer be the same person who sent the email? Desperate to understand what's going on, Camryn starts to look into who the reviewer might be. Other authors warn her that trolls are dangerous, that she should be careful, but the actions of the troll are escalating, and Camryn's starting to lose touch with what's real and what isn't. When the troll's harassment turns deadly, it will take everything Camryn has to unmask the enemy who's been sabotaging her every move -- and finally learn why she's being targeted"-- Provided by publisher.
