Gregor and the Prophecy of Bane (The Underland Chronicles, Book 2) - Suzanne  Collins
This second novel proves that series has something special about it that elevates above your standard youth-hero-quest type novel. It's fun, fast-paced and, if I'm honest, a wee bit predictable, but also very thoughtful. I say if the premise sounds remotely appealing to you - give this series a chance! I can't wait to read the next installment!
