for Cosmic Commandos by Christopher Eliopoulos
Jeremy and Justin are twins, but they couldn't be any more different from each other. Jeremy is a risk taker who likes to get his hands dirty; Justin prefers to read, focus, and get all his facts straight before jumping in. But they do have one important thing in common: They both love video games. When Jeremy wins a cereal-box charm that brings his favorite video game to life, villains and all, he finds that he's in way over his head. Justin knows everything there is to know about the rules of the game--he read the handbook, of course--and Jeremy isn't afraid to try new things. Can these two mismatched brothers work together to beat the video game that has become their life?
