Apparently writing novels is more fun than running a TV show for David S. Goyer. The FlashForward executive producer who dropped out as the series' show runner has embraced another calling. Goyer and TV writer/author Michael Cassutt have signed a three-book deal with Penguin's imprint, Ace Books, to write a sci-fi adventure trilogy, including Heaven's Shadow, Heaven's War and Heaven's Fall, according to Variety.
