A debut illustrated middle grade adventure novel from bestselling author and illustrator Vera Brosgol (creator of Anya's Ghost, Be Prepared, and Plain Jane and the Mermaid), where magic, mystery, and a marvelous mailbox take two kids on an incredible journey.

Be careful what you wish for… After everything they’ve been through, Oliver and his mum finally have a place to call home. But Oliver’s fresh start feels more like a dead-end at his fancy new private school, where kids fly in on helicopters, wear the latest and most expensive sneakers, and go on luxury vacations. Oliver is only there because his mum’s the school custodian. Oliver wishes his life could be easier. And then one day, after slipping a wish into a mysterious mail slot, it suddenly comes true. Pizza for dinner? Yes! The rarest sneakers in the world? Yes! Everything he could ever want, without spending a cent? Yes, yes, yes! Oliver’s dreams are finally within his grasp… but what happens when he discovers that his wishes don’t come for free?
