How to Finish a Novel

To get my novel finished I've decided to enter this competition. The prize is amazing - £10K and a publishing deal. The deadline is a month away. It's good to have a deadline and I like a challenge, but it means I must not only finish my second draft (rewriting at least one chapter per day for the next three weeks), but I also need to pick and polish the best 5,000 words and write a brilliant synopsis - simples!
I've been rewriting the entire first draft from multiple third person POVs into one first person POV as well as tweaking the plot, shaping the structure and tightening the prose. It's not been easy but it's definitely improved the first draft.
Because of family responsibilities I can only write very early in the morning or late at night, creating a steady cycle of sleep deprivation. Add in a few restless nights with R and my poorly tooth and it's quite possibly a recipe for disaster. So I have one month in which to achieve a miracle - let's hope it's worth it! :)
