Rockets Versus Gravity

(N.B. I'm a student of the author's and have come to know him personally.)

Very crisp read filled with characters that are easy to identify with. The morality of the book divides the characters into haves and have-nots, and invariably it's the have-nots who find freedom from their situation, and find value in things other than... things. Lots of hope. Lots of humour.
