He is the author of forty novels, ninety short stories, and the odd odd poem, and has also written in universes created by other people, such as those of Star Wars and Doctor Who. His work has won awards, debuted at number one on the New York Times bestseller list, and been translated into numerous languages. His latest novel is Twinmaker, the first in a new series that takes his love affair with the matter transmitter to a whole new level (he just received a PhD on the subject, so don’t get him started).
