Things are going GREAT with the rewrite. (I feel like I might jinx myself saying that, but it's true!) I got a ton done yesterday and am finally getting to the point where I'm not mourning the first version...as much.
I'm happy with the new way it's going, and the main bones of the story seem to be finding their back in. THAT was my fear, that everything I loved about version 1.0 would be gone, and that doesn't seem to be happening.
A friend and I have been exchanging chapters (she's writing an awesome book too!), and that has helped motivate me to keep at it.
