It's not a huge problem--I don't have to scrap the whole thing and start over--but it's significant.
Initially, I'd planned on a BIG FINISH, I staged certain events to build up to that finish, but I no longer like that finish. It was flashy, impressive... and impersonal, and the story is all sorts of personal.
I think I many have to reorganize events in the last 3 or 4 chapters, which will mean going back even further to tweak other events so that my timeline doesn't get totally messed.
GRRR! Phaw! *whimper*
Oh well. The recipient has waited this long. Another couple months can't be that unexpected.
(on a side note, I'm about three quarters through the second re-write of The Wounded. It's going a lot easier than Third Wheel.)
