“It’s set a few months after the series’ final episode, The Great Leap Forward, and it will build upon events depicted in Greg Cox’s forthcoming post-finale 4400 novel, Promise City,” he explains.
“In a lot of ways,” he adds, “I approached Promises Broken with the mindset of crafting the ‘grand finale’ tale the show might have done if its final six episodes had been allotted a budget of two hundred million dollars. A lot of the lingering story threads and dramatic questions from the end of season four will be dealt with in Promises Broken. Its storyline, which has just been given the green light by the licensor, has been described as ‘epic’ and will kick over the status quo of the series.”
As one of only two authors writing post-finale books for that series, it seems possible that David will have a fair amount of influence on the direction of the line, but he disagrees. “I’m writing the last scheduled book in the series, which means I get to wreak havoc on the series’ status quo and the characters’ lives, but unless the book sells like gangbusters and spurs Pocket to extend its commitment on that license, I’d say my ‘influence’ on the line will be minimal.” On the other hand, that’s also had a positive effect for him, since on the creative-freedom front he “was all but given carte blanche.”
