Atticus's friends invite him to go trick-or-treating. He has never been trick-or-treating because most houses in his neighbourhood have steep driveways and front steps. It's too difficult to get his wheelchair up to the doors. His friend Siena has a smart and simple idea so Atticus can join in the fun on Halloween night. Before you know it, Atticus's other friends come up with a great idea to transform his wheelchair into a one-of-a-kind costume!
