Kathryn Dance (abridged)

Ten years ago in California, Daniel Pell, a self-styled Charles Manson, was sentenced to life in prison for murdering an entire family: husband, wife, and two children, plus one of his young male followers. He is brought to Salinas, California, to interview with Kathryn Dance after he is implicated in yet another killing. Things go terribly wrong during an interview break, and Pell escapes, intent on killing again.

A highway patrol trooper notices something strange on the side of the road: a homemade cross, fashioned as a memorial. Except the date being 'remembered' is the following day - the day the police find a kidnapped teenage girl in the trunk of a car, left for dead. Special Agent Kathryn Dance, the kinesics expert with the California Bureau of Investigation, is on the case.

The Monterey Peninsula is rocked when a killer begins to leave roadside crosses beside local highways -- not in memoriam, but as announcements of his intention to kill. And to kill in particularly horrific and efficient ways: using the personal details about the victims that they've carelessly posted in blogs and on social networking websites.
