Last Fall, Cynthia Rothschild saved her best friend from the demon librarian, Mr. Gabriel.

But now all that stuff is over, and Cyn is ready to have the best summer ever - at theater camp (!) with her former crush and now boyfriend (!!) Ryan Halsey. Once Cyn gets to camp, though, nothing goes according the plan. Worst of all, it turns out the demon stuff isn't as over as she had hoped. At least any new demons that show up to ruin her summer can't possibly be as evil as Mr. Gabriel, who is, thankfully, very dead now. It's not like he could come back to life to seek his terrible revenge or something. Right?
