Have just written 'The End' in my notebook. (Cue triumphant playing of the Hallelujah Chorus). All I have to do now is type up the last 4000 or so words of the book.
I had a writing frenzy last night and this morning, and I have finally finished. The idea for this book has been in my head for over two years now, and I've loved writing it (hope my editor likes it as much), but I am so relieved to have it out of me. Now I just need to tweak and polish and make it as shiny as can be before I hand it in.
