Chester has always wanted to become a service dog. When he fails his certification test, though, it seems like that dream will never come true until a family adopts him. They want him to be a companion for their ten-year-old son, Gus, who has autism. But Gus acts so differently than anyone Chester has ever met. He never wants to pet Chester, and sometimes he doesn t even want Chester in the room. Chester s not sure how to help Gus since this isn t exactly the job he trained for but he s determined to figure it out. Because after all, Gus is now his person.
