One-Eyed Jacks
The Jumpers are a fictional criminal gang in the Wild Cards anthology series, first appearing in "One-Eyed Jacks", the eighth book of the series. Various jumpers continue to play a major role in the next three volumes of the series, Jokertown Shuffle, Double Solitaire, and Dealer's Choice. Originally thought to be a lone ace, known to the media as the Jumper, simultaneous jump attacks in different locations eventually revealed that there was more than one of them.
