He also started and edits a series called Wild Cards.
Set during an alternate history of post-World War II United States, the series follows events after an airborne alien virus is released over New York City in 1946 and eventually infects tens of thousands globally. The virus, designed to rewrite DNA, was developed as a bioweapon by a noble family on the planet Takis, and it is taken to Earth to test on humans, who are genetically identical to the people of Takis. Dr. Tachyon, a member of this family, objects and attempts to stop them. However, his attempt crashes their ship, releasing the virus.
The virus affects each individual differently, and it becomes known as the Wild Card virus because of these "random and unpredictable" symptoms. It kills 90% of those who contract it and mutates the remaining percentage. Of that remainder, 9% are Jokers, who develop minor or crippling physical conditions. 1% are Aces, who remain human or mostly human in appearance but develop superhuman abilities; Aces whose abilities are too trivial or specific to be generally valuable are called Deuces.
So he writes some of the stories, gives the rest of the writers overviews of the plot points of the book and then edits them all together so it is a series of short stories that end up telling a complete story. They have a bunch of books at this point and I really liked them.
