In addition to the Alcatraz series, Sanderson also has the Mistborn trilogy (described on his website as “a hybrid fantasy, heist story, kung fu epic”), several standalone books, and he has also been chosen to finish Robert Jordan’s series The Wheel of Time (after Jordan’s death in 2007).
If the Weasley clan is your favorite part of the Harry Potter series, you need to pick up Alcatraz Versus the Evil Librarians. Its dominant asset is humor, but Sanderson never shortchanges the conflict, action, or tension. Three books are already out, and there are two more in the works. By the looks of it, Sanderson’s imagination isn’t going to run out of quirky ideas anytime soon.
