And no we are not talking about Robert Johnson, founder and former owner of B.E.T.
Black Trump is a novel in a series of science fiction/superhero novels created by a group of writers in New Mexico. The entire group would write and individual story and somehow the editor would string these stories together into a cohesive novel.
The fifteenth volume (dubbed "Book III of a New Cycle") in the Wild Cards shared universe fiction series edited by George R. R. Martin. Published in 1995, it is the final book in the "Card Sharks" cycle, with the completion of the Black Trump virus (fatal to anyone with the Wild Card infection) and its release in the world. Unlike the two previous books, Black Trump was a mosaic novel, much like Jokers Wild and Ace in the Hole.
