Alcatraz Versus the Evil Librarians
By Brandon Sanderson [LibraryThing — Amazon]
Aside from being an orphan raised in a string of foster homes, and aside from his unnerving tendency to break everything he touched, and aside from his ridiculous name, Alcatraz Smedry was a more-or-less normal kid. At least, until the inheritance his parents left him finally got delivered. It turned out to be a bag of sand, which was weird enough; weirder still, that bag of sand was immediately stolen by an evil librarian, and Alcatraz learned that, if he didn’t get his sand back, the consequences would be dire.
