When John Riley catches the wrong bus, he ends up on Hyperspace High- and amazing school on a spaceship!

Light years from home, John makes friends with aliens, struggles through Galactic Geography lessons, and eats gross Martian food in the canteen. But John needs to get up to speed fast, or he’ll be booted back to Earth. Will an asteroid storm on a school trip give him the chance to prove that you don’t have to be top of the class to be a hero?
