Life begins anew for 100 Martian colonists, as they study and inadvertently begin terraforming the planet, while splinter groups threaten to break up the colony.

Completely different from anything I've read before.  It was tough to see why he chose the characters the way he did, but then, when it started coming together, I thought I saw why.  But as they formed a human society on Mars, and others came, and problems arose, and rebellion started, it was just too much to handle.  Really tough to evaluate this book.  Some good parts, some hard to read areas.
