It was only a matter of time before Ruby's father would kill her. Or she would kill him. Flawless Murderers is a twisted murder mystery, through the eyes of the killer and her witness, as they do everything in their power to cover up her guilt. Once the best of friends and still next-door neighbors, Eli and Rue haven't spoken in four years. While Eli clings to their childhood like glue, Ruby only longs to break away from the never-ending cycle of abuse she is stuck in, even if that means hurting people she loves in the process. When she decides her only choice is to slip fatal drugs into her father's drink, ending his life, Eli doesn't hesitate to be her false alibi and steer the police's suspicions toward himself instead. As their stories intertwine, the teens must find ways to face their family problems, unspoken longings, and guilt without jeopardizing their chances at freedom. Someone knows what Rue did, and the friends must find out how to keep this anonymous blackmailer quiet before she ends up in jail for doing what she once thought was the right thing.
