In the middle decades of the twenty-first century, the corporate powers on Earth have established a thriving colony on Mars as an alternative to life on the overpopulated, war-torn, ecologically ravaged home planet. But when the economy of EUPACUS—Earth's collective industrialized nations—collapses, all contact between the two worlds abruptly ceases, and the Martian pioneers are left to fend for themselves. Led by Tom Jeffries, a philosopher and a visionary, the colonists now face a twofold challenge: No longer supported and subsidized by Earthbound interests, they must somehow form a working planetary alliance to create a new society based firmly in freedom and fairness for all while at the same time eliminating war, hunger, hatred, environmental abuse, and other former scourges of humanity. But first and foremost, they must survive.

Brian W. Aldiss, a Hugo and Nebula Award-winning Grand Master of Science Fiction, presents a vision for the future that is startling, uplifting, and endlessly exciting. Written in collaboration with noted mathematician and physicist Roger Penrose—and with essential input from international law expert Laurence Lustgarten—Aldiss's remarkable White Mars opens a window onto a relentlessly thrilling and gloriously possible tomorrow.
