Ben 10: Secrets of the Omnitrix

Ben is back! After the events of Danger Watch, Ben is still no closer to understanding what the Omnitrix is, or why it stuck itself on his wrist. As he, Gwen, and Granpda Max make their way back to Bellwood, they'll have to go through power-crazed sorcerers, monstrous mutants, and mad scientists before they can discover the Secrets of the Omnitrix. (Danger Watch: Phase 2, Book 2)
