The Expanse novels by James S.A. Corey (the pseudonym for writers Ty Franck and Daniel Abraham) imagine how human beings would colonize our solar system -- until Earth looses control of its vast empire, and the colonies break into warring factions. The books are international best-sellers and the TV adaptation on the Syfy network has been critically acclaimed. Ty Franck, Daniel Abraham and one of the show's producers Mark Fergus discuss how The Expanse was developed, and why its underlying message feels more urgent than ever.
