I write stories, and I also don't write them from start to finish, so maybe that is why I read books that way. I tend to write the beginning of a story first, then the end, then the long middle. I feel like I can't write the story properly unless I know where it is going. The events in the beginning and middle must foreshadow the end, so I need to have the end written fairly early on so I know where the story is headed. if that makes sense....
