The most challenging nonfiction has been Heaven. The most challenging fiction has been Dominion. They were my biggest books, requiring extensive research. (I collected and read 150 books on heaven written over the last three hundred years.) And, of course, the more you research, the more work you create for yourself later as you really want to include something but there’s no room for it!
