Eighteen years ago, FBI profiler Evelyn Baine's best friend, Cassie Byers, disappeared, the third in a series of unsolved abductions. Only a macabre nursery rhyme was left at the scene, a nursery rhyme that claimed Evelyn was also an intended victim. Now, after all these years of silence, another girl has gone missing in South Carolina, and the Nursery Rhyme Killer is taking credit. But is Cassie's abductor really back, or is there a copycat at work?

Evelyn has waited 18 years for a chance to investigate, but when she returns to Rose Bay, she finds a dark side to the seemingly idyllic town. As the place erupts in violence and the kidnapper strikes again, Evelyn knows this is her last chance. If she doesn't figure out what happened to Cassie eighteen years ago, it may be Evelyn's turn to vanish without a trace.
