When a BIG, lovable, does-it-her-way dog wiggles her way into the heart of a loudmouth pipsqueak of a boy, wonderful things happen that help him become a bigger, better person. Timminy knows that moving to a new town just in time to start middle school when you are perfect bully bait is less than ideal. But he gets a great consolation prize in Maxi - a gentle giant of a dog who the family quickly discovers is deaf. Timminy is determined to do all he can to help Maxi - after all, his parents didn't return him because he was a runt. But when the going gets rough for Timminy, who spends a little too much time getting shoved into lockers at school, Maxi ends up being the one to help him - along with their neighbor, Abby, who doesn't let her blindness define her and bristles at Timminy's "poor-me" attitude. It turns out there's more to everyone than what's on the surface, whether it comes to Abby, Maxi, or even Timminy himself.
