The methods are opposed by those determined to preserve their home planet's hostile, barren beauty. Led by the first generation of children born on Mars, these rebels are soon joined by a handful of the original settlers. Against this cosmic backdrop, passions, partnerships, and rivalries explode in a story as spectacular as the planet itself.
