A review by bookgirl4ever
Boom! by Mark Haddon

3.0

Jim and his friend Charlie spy on the teachers in the teachers' lounge with walkie talkies. They overhear two of their teachers (ones who are never seen speaking to each other in public) speaking some weird language together. They decide to investigate and become involved in something completely unexpected and dangerous.

Funny and a quick read. For fans of Bruce Colville. Older elementary aged.
