I read an article with Neil Gaiman and Terry Pratchett regarding the writing of Good Omens. In it they claimed to frequently find brilliant lines and compliment the other, only to have the other claim they never wrote the line. They said that by the end, they were certain the book had secretly begun to write itself. This weekend I read my manuscript cover to cover and found more than one instance where I thought, I didn't write that! (It was far to good to have been me.) Unlike Gaiman and Pratchett, I have no partner in crime who could have done some editing while I wasn't looking. Does anyone else ever get the feeling that your book has begun to write itself?
