The return of the famous shared-world superhero books created and edited by George R. R. Martin, author of the A Song of Ice and Fire series.

ALL ABOARD, IF YOU DARE.

In the aftermath of World War II, the Earth’s population was devastated by a terrifying alien virus. Those who survived were changed forever. Some, known as jokers, were cursed with bizarre mental and physical abnormalities; others, granted superhuman abilities, are the lucky few known as aces.

In this volatile and divided world, intrigue and violence are never far away and a trip up the Mississippi River aboard the steamer Natchez is no exception. Boats full of joker refugees spark conflict between super-powered aces. Zombies and vast alligators lurk beneath the water. And in the steam of the engine room, a spirit stands ready to defend its riverboat home.

Edited by Number One New York Times bestselling author George R. R. Martin, Mississippi Roll features the writing talents of Stephen Leigh, David D. Levine, John Jos. Miller, Kevin Andrew Murphy, Cherie Priest, and Carrie Vaughn.
