Word Meter (which you'll find over in the righthand column Quick Status section), I'm at the 82% mark in completing a major revision to my WIP. "Major," in this case, means skewing the whole focus of the book, writing new scenes, deleting old scenes (more than 10,000 words so far), shifting some scenes around, and rethinking the overarching theme of the book.
What's left, however, is revising the ending. You think beginnings are hard? Endings are murder.
I'm over at the Castles & Guns blog today, talking about writing endings to novels and one particular book whose ending drove me nuts. Click on the link, come on over and leave a comment!
