I've been writing on Lost! Which will be a companion piece for On Dog Creek. One of the things which is taking a lot of time is the length of the chapters. To put it in perspective I have about two chapters written and the story is already nearly a third as long (or more) in word count as On Dog Creek.
I doubt that I will be any less than 7000 words for just two chapters. At that rate I expect that Lost will be at least twice as long as On Dog Creek.
