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.



A funny, pacy adventure that blends a fairly kitchen sink set of family dynamics with some utterly zany fantasy. The whole thing is a pleasure to read and I think probably a pleasure to share reading aloud. There is a big whiff of Roald Dahl anarchy about it, especially in the way the adults are awfully bad or bumblingly hopeless. The children save the day just as children should.
