It started as just another quiet summer in the tiny town of Granger, Texas, for 12-year old Toby Wilson. That was before Granger turned into a virtual circus, when Zachary Beaver, “the fattest boy in the world” comes to town. In his trailer decorated with colored lights, Zachary is his one-man sideshow – eating everything he can find, barking orders through his thick New York accent and giving these small-towners a dose of attitude with a capital A. The whole town gathers around to gawk at Zachary, who in turn gawks back. But, Zachary is more than just an overweight kid with an attitude – much more, as Toby and his friends quickly find out. When Toby and his best friend Cal visit Zachary to find out what this kid is all about, they get more than they bargained for. Out of this first visit, Toby and Cal see the vulnerability behind the rough exterior and a friendship develops between the three. This odd relationship blossoms into a wondrous journey that leads them through what will be a life-changing summer.
