Alcatraz versus the Evil Librarians by Brandon Sanderson (teen)

It's about time someone realized librarians' innate capacity for evil and mayhem! I knew I would like this book from the first sentence, which I quote here in its entirety: "So, there I was, tied to an altar made from outdated encyclopedias, about to get sacrificed to the dark powers by a cult of evil Librarians." And I was not disappointed. Hoping mightily for a sequel!
