@GelidaRainclaw If you do not mind, I like to add an opinion. Of course, the choice is also yous to make. But I thought that maybe... you could... um, restart (Option 3). I think (my opinion, as well as experience as a writer) it is better to start fresh. If you have an idea and a guide line, the book will make more sense than continuing off where you left after a bit of time off. It might be confusing to the readers if you have more ideas that might contradict the previous chapters. Additionally, you might have gained more experience and want to incorporate it in your story. Like I stated before, this is only an opinion, you need not take it to heart. I just wanted to..., help, I guess? Thank you anyways for taking time and reading this. Best of luck to your book and hope that it will bring you joy writing with it again.
