The Girl Who Was Left

Everyone has something, something that gets stuck in their heads and refuses to leave. Penny Nickels was Zoe's thing. Maybe Zoe could move on if there had been a body or a scrap of evidence to hint at something other than her disappearing off the face of the Earth. Maybe that was why Zoe was driven to become a homicide detective for the FBI. But that wasn't what mattered now. What mattered was the case of Darcy Williams, whose disappearance perfectly paralleled Penny's. After returning to her home town, Zoe discovers that the roots of this mystery go much deeper and much further back than Penny and Darcy. Can she discover the truth and figure out a way of stopping a phantom foe before another little girl is taken?
