Wondering what other people's experience may have been like if they've gone through something similar I'm going through. Basically, I've been writing a sci-fi novel on and off for several years now. Been pacing it as a thriller. But after a lot of internal digging, and editing, etc. I've come to the realization that I'm not getting what I want out of it by pacing it like a thriller. I'm just not feeling as immersed as I would like it to be. I've re-drafted some chapters now at a longer length and really loving it. But now I feel like the entire idea of the pace and character of the novel is shifting from what I've had in mind for the last few years. In a way, I'm mourning what I've worked on as part of the process to move towards what I know I really want it to be. Has anyone else here done this after working on something so long? Good or bad experiences doing it?
