Mississippi Roll: A Wild Cards Novel is an adventurous journey along Ol’ Man River, featuring beloved characters from the bestselling shared-universe science fiction superhero series, edited by #1 New York Times bestselling author George R. R. Martin.

Now on its final voyage, the historical steamboat Natchez is known for her super-powered guest entertainers. But after the suspicious death of a crewmember, retired NY police detective Leo Storgman decides to make this incident his personal case. His findings only lead to a growing number of questions. Is there some truth behind the ghostly sightings of the steamboat’s first captain Wilbur Leathers? What secret does the current captain seem to be hiding? And could the Natchez be ferrying mysterious – and possibly dangerous – cargo onboard?

Mississippi Roll features the writing talents of Stephen Leigh, John Jos. Miller, Kevin Andrew Murphy, Carrie Vaughn (Martians Abroad), Hugo-Award winning author David D. Levine (Arabella of Mars), and Hugo and Nebula Award finalist Cherie Priest (Boneshaker).

Now in development for TV: Rights to develop Wild Cards have been acquired by Universal Cable Productions, the team behind The Magicians and Mr. Robot, with the co-editor of Wild Cards, Melinda Snodgrass, as executive producer.
