Nearly a generation has passed since the first pioneers landed, but the transformation of Mars to an Earthlike planet has just begun. The plan is opposed by those determined to preserve the planet's hostile, barren beauty. Led by rebels like Peter Clayborne, these young people are the first generation of children born on Mars. They will be joined by original settlers Maya Toitovna, Simon Frasier, and Sax Russell. Against this cosmic backdrop, passions, rivalries, and friendships explode in a story as spectacular as the planet itself.
