An interesting book. The characters seemed a bit flat at first glance, but when you look closer, there was more depth. The technology was well handled and believable, and the military tactics rang true. The plot was obviously taken from Heinlein's "The Moon is a Harsh Mistress"; the moon has become the breadbasket for a dangerously overpopulated Earth, but the people who produce the food are very disenfranchised, having no true representation in government, though they don't seem to be as obviously mistreated as the Loonies in "Harsh Mistress". The end was somewhat of a surprise; however, I'm not sure that I *liked* the end....a whole new element was added to the plot at the last minute, and it was kind of jarring.
