Toppling

John lives for that satisfying clink of dominoes as they topple in a perfectly timed rhythm of his own design. His sister thinks he's a dork, but all he cares about is setting the world record for knocking down dominoes -- that and hanging out with his best friends at school. But when his closest friend, Dom, gets sick and ends up in the hospital, John and the gang are left behind, wondering what to do for him. Author Sally Murphy shows what a group of friends, together with an unlikely ally, will do to keep the world of one of their own from toppling.
