Senior year is finally over. After all they've been through, Dan, Abby, and Jordan are excited to take one last road trip together, and they're just not going to think about what will happen when the summer ends. But on their way to visit Jordan's uncle in New Orleans, the three friends notice that a black muscle car appears to be following them. Then Dan starts receiving phone messages from someone he didn't expect to hear from again—someone who died last Halloween.

As the strange occurrences escalate, Dan is forced to accept that everything that has happened to him in the past year may not be a coincidence, but fate—a fate that ties Dan to a group called the Bone Artists, who have a sinister fascination with notorious killers of the past. Now Dan's only hope is that he will make it out of his senior trip alive.

In this third book in the New York Times bestselling Asylum series, found photographs help tell the story of three teens who exist on the line between past and present, genius and insanity.
