Boom!

von Mark Haddon

Boom! Is a roller-coaster read with spaceships, spies and mortal danger!

Jim and his best friend Charlie weren¿t looking for adventure, when they decided to bug the staffroom . . . But then they overhear their teachers speaking in a secret language and it¿s too late to turn back. And now they have to explain to the police, the headmistress and their parents where they¿ve been for a whole week ¿ without mentioning the aliens.
