Muscle teen titan Alex Johnson is starting his senior year in High School. Alex has spent most of his life seemingly invisible, but since an experimental genetic treatment to save his life, he’s literally Big Man on Campus. His friends think that Alex is large and in charge, so the school bullies won’t be a problem anymore, but the bullies have other ideas. Meanwhile, Alex is just trying to cope with the usual problems—peer pressure, sports, grades—and a suddenly rocky relationship with his first real boyfriend. Along the way, Alex reaches out to some of the geekiest freshmen in school-- something no one ever did for him-- and his plan to help them produces some startling results.
