Predator or prey? On the Internet, how can you tell? When private investigator Abby Maxon answers a call for help from an old college friend, she never expects to find herself searching for a missing teenage girl. Abby investigates accidents and tracks down reluctant witnesses for a living. The last thing she wants is to get involved in a missing person case, especially when that case leads to murder. Pretty fifteen-year-old Rachel Ellison got in over her head when she played a flirtatious Internet game of "let's pretend" with a married man. Now Rachel's dead, Abby's friend is the prime suspect, and the only clue to the identity of Rachel's killer is a ceramic horse missing from the dead girl's bedroom. The Internet can be a dangerous place for the unwary, including Abby's own teenage daughter, another pretty fifteen year old who wants to meet a boy she's only talked to online.
