Thirteen - Richard Morgan

Thirteen is a novel about the not too distant future when Mars is past the initial stages of colonization and America has splintered into Rim states and Jesusland. Sounds almost prophetic after last night. In this twisted future there are Thirteens. They're genetically engineered human throwbacks to pre-agricultural society when the survival of humans depended on aggression and individualism. Thirteens were designed to give humanity the edge they needed to win wars and escape the general feminization of society. This story is excellent. It was very hard to put down. I'm hoping for a sequel. Very highly recommended.
