This is a seven-chapter story in which Bones and Booth solve a serial-kid-killer case and progress from friends to significant others. The case was well-plotted and interesting, with time pressure, a surprise, and use of Bones' anthropological skills. The love story did not feel too forced, which can sometimes be a problem.
