Fantastic book in a even more fantastic trilogy. (there is a fourth novel out as well) This has to be one of the best series on colonization of Mars than any other I have ever read...and I've read thousands!
If you like epic sagas with superb characterization & good science, you MUST read these!
The first volume, "Red Mars," is brilliant, masterful, and thrilling. Robinson writes convincingly on nearly every vector that a believable space colonization narrative needs to touch on: the technological, the ecological, the infrastructural, the psychological, the political.
