Geoff Ryman is a Canadian living in London England. His science fiction and fantasy novels include The Warrior who Carried Life, The Child Garden, Lust and Air. His more mainstream fiction includes Was, 253, and The King's Last Song. His fiction frequently is set in versions of Cambodia, from that last novel in the list to the Hugo and Nebula nominated Pol Pot's Beautiful Daughter. Overall his fiction has won 14 awards. He named and is key member of the Mundane group of SF writers who advocate fiction more grounded in current science. He is currently working on an anthology of stories that are collaborations between fiction writers and scientists. He reserves, as you see, the right to write fantasy when he chooses, and agreeing to write Mundane fiction doesn't mean that he doesn't enjoy Dr. Who.
