Gr 5-8-Tom is not a happy middle schooler. He lost his father two years ago, he keeps getting into trouble, and his only friend is an imaginary twin brother, Eddie, who lives on an Earth that is 50 years behind his own. But it turns out that Eddie is not imaginary. There really is an Earth2, and the brothers find out that both worlds are in trouble. The alien scientists who created the planets believe them to be a failed experiment and are ready to destroy them, and Tom and Eddie must switch places to try to thwart their plan. An exciting premise, short chapters, and plenty of action make this a good choice for reluctant readers, and the ending promises future installments.-Laurie Slagenwhite Walters, Peachtree Montessori International, Ann Arbor, MIα(c) Copyright 2011.
