Will it finally be curtains for the demonic Mr. Gabriel in this climactic chapter of the Evil Librarian series? After sending the evil librarian, Mr. Gabriel, back to the demon world once and for all at theater camp last summer, Cynthia is ready to enjoy a completely demon-free senior year of high school, especially once she learns the fall musical will be Les Misérables . She can't wait to create the most incredible barricade set design in all of high-school theater. And her boyfriend, Ryan, is sure to land his dream role of Javert. But down in the demon realm, an epic mishandling of Mr. Gabriel's essence leads to his escape -- and soon he's gathering strength, bent once again on revenge against Cyn and everyone she loves. Best-selling author Michelle Knudsen's Evil Librarian series overflows with horror and humor -- and it looks like this show's got a third act.
