Matthew Quick reveals plot of new book

Today, we have a Q&A with Matthew Quick, the author of locally-set "The Silver Linings Playbook," which is being adapated into a film starring Bradley Cooper and Robert De Niro. Quick releases "Boy21," his third novel -- and his second geared at teenagers -- next week.

Quick also talked to us about what he's working on, including a return to adult fiction that he kept mum on because it wasn't finished yet. Quick's next book is "Forgive Me Leonard Peacock," another YA book. "It’s about a kid who decides to kill his former best friend and then himself and the hope he finds in a very unlikely way," Quick said.

So, not light reading material?

"No," Quick said, laughing. "This is one is very intense and very different. But I think people will see the theme of mental health in all of my books. I think it’s very much thematically consistent with my other works."

"Boy21" is about Finley, a quiet kid from a blue collar, Philly-area neighborhood, who is forced to befriend Russ, a priviledged kid with a tragic past who believes he's from outer space. It hits bookstores a week from today. Quick will do a signing at Collingswood High School on Monday. Check the trailer for the book:
