While I am a fan of Kim Robinson's work, I found it difficult getting into these novels, even after I'd found out that James Cameron had optioned them for the film rights. Still and all, Green Mars is a cut above the usual mass market fiction, but be warned, it's really involved. Part 3 of his "Mars Trilogy".
Kim Stanley Robinson has earned a reputation as the master of Mars fiction, writing books that are scientific, sociological and, best yet, fantastic. Green Mars continues the story of humans settling the planet in a process called "terraforming." In Red Mars, the initial work in the trilogy, the first 100 scientists chosen to explore the planet disintegrated in disagreement--in part because of pressures from forces on Earth. Some of the scientists formed a loose network underground. Green Mars, which won the 1994 Hugo Award, follows the development of the underground and the problems endemic to forming a new society.
A wonderful sequel to "Red Mars," this book tells the story of the second generation in Robinson's Martian world. Terraforming is continuing, of course, but the ongoing political (and sometimes physical) struggle between competing interests both within the Martian community and back on Earth is what really makes this story shine. Robinson continues to use his rich web of characters and well-researched scientific plot elements to great effect here. I can't wait to pick up "Blue Mars!"
