The Shattered Lens : Alcatraz vs. the Evil Librarians

Now in paperback for the first time, featuring all new covers, the Alcatraz Versus the Evil Librarians middle-grade series from #1 New York Times bestselling author Brandon Sanderson
Alcatraz Smedry is up against a whole army of Evil Librarians in this fourth adventure, with only his friend Bastille, a few pairs of glasses, and an unlimited supply of exploding teddy bears to help him. This time, even Alcatraz’s extraordinary talent for breaking things may not be enough to defeat the army of Evil Librarians and their giant librarian robots.
