Winner of the Hugo Award for Best Novel • One of the most enthralling science fiction sagas ever written, Kim Stanley Robinson’s epic trilogy concludes with Blue Mars—a triumph of prodigious research and visionary storytelling. “A breakthrough even from [Kim Stanley Robinson’s] own consistently high levels of achievement.”—The New York Times Book Review The red planet is no more. Now green and verdant, Mars has been dramatically altered from a desolate world into one where humans can flourish. The First Hundred settlers are being pulled into a fierce new struggle between the Reds, a group devoted to preserving Mars in its desert state, and the Green “terraformers.” Meanwhile, Earth is in peril. A great flood threatens an already overcrowded and polluted planet. With Mars the last hope for the human race, the inhabitants of the red planet are heading toward a population explosion—or interplanetary war.

The tranquility of Mars is disrupted by humans who want to conquer space, colonize the planet, and escape a doomed Earth.

Novelist J. D. Landis switches gears and writes some delightfully silly, fun, and sometimes poignant poems for kids.
