Asylum

Ricky Desmond has been through this all before. If he could just get through to his mother, he could convince her that he doesn't belong at Brookline. From the man who thinks he can fly to the woman who killed her husband, the other patients are nothing like him; all he did was lose his temper just a little bit, just the once. But when Ricky is selected by the sinister Warden Crawford for a very special program - a program that the warden claims will not cure him but perfect him - Ricky realizes that he may not be able to wait for his mom a second longer.

When Dan, Abby, and Jordan meet Oliver in Catacomb - the third book in the Asylum series - he is a mysterious young antiques dealer with a dark past. But before he was stuck in America's most haunted city, he was a teenager with a bright future ahead of him. In this story we find Oliver saving up to attend his dream college in the fall and leave behind his family's New Orleans antique shop for good. And if his job just happens to involve robbing graves for a group calling themselves the Bone Artists, well - money is money, and it's only for now.

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 they're being followed...and photographed. Then Dan starts receiving messages from someone he didn't expect to hear from again - someone who died last Halloween.
