Perfect Timing is a young adult novel (10-12 year olds) about Andrew, a child with a disability, who has the band the Angry Wombats move in across the road from his home. They befriend him and he learns to play guitar and sets up a band with his school friends. He discovers his disability doesn't stop him succeeding in music.
