This question contains spoilers… (view spoiler)[I was surprised, but not disappointed, by the way that the book ended.

Your book is not like that, and as a result ended up staying with me longer than a "normal" book. Did you and Tim vacillate back and forth over the way it would end, or did you always have something like this in mind? (hide spoiler)]
