To celebrate, Tor Books is re-releasing Wild Cards, the original anthology. This is not just any old re-release, however; the new edition is upgraded with three all-new stories.

Product Description: Back in print after a decade, expanded with new original material, this is the first volume of George R. R. Martin's Wild cards shared-world series

There is a secret history of the world--a history in which an alien virus struck the Earth in the aftermath of World War II, endowing a handful of survivors with extraordinary powers. Some were called Aces--those with superhuman mental and physical abilities. Others were termed Jokers--cursed with bizarre mental or physical disabilities. Some turned their talents to the service of humanity. Others used their powers for evil. Wild Cards is their story.

Originally published in 1987, Wild Cards I includes powerful tales by Roger Zelazny, Walter Jon Williams, Howard Waldrop, Lewis Shiner, and George R. R. Martin himself. And this new, expanded edition contains further original tales set at the beginning of the Wild Cards universe, by eminent new writers like Hugo--winner David Levine, noted screenwriter and novelist Michael Cassutt, and New York Times bestseller Carrie Vaughn.
