There will be two fiction books out next year but Hall Monitor has it right, we're not quite there yet in releasing official info on those other than the titles, which Stephen has mentioned when he was on his book tour for Doctor Sleep. The titles are Mr. Mercedes and Revival.
The moderator also confirmed that King will NOT do any book tours during 2014.
He's taking 2014 off--no book tours. There will be two books out next year--he's already written them--but he won't be doing book tours for them.
