Lipsyte (Center Field, 2010) departs from his usual sports themes in this tale of aliens, parallel worlds and middle school. Tom is a smart, talented loner with a chip on his shoulder and a big secret: an imaginary twin on another planet. Eddie is Tom's identical twin and polar opposite--athletic and popular and his planet is fifty-some years in the past. The twins are caught up in an alien master plan that might just mean both Earths will be destroyed. They switch places, slip between planets and uncover deep secrets. In their fight to thwart the alien scientists, Tom and Eddie must face unimaginable dangers!
