There are three more full days until the start of National Novel Writing Month, and that means that yet another software developer has checked in with a deal on a Mac writing application.

This time, it's Mariner Software, and the application is StoryMill. Mariner's deal is this -- if you purchase StoryMill before the start of NaNoWriMo on November 1st, you'll get a 35% discount off of the normal price of US$49.95. That brings the price down to a very nice US$34.95.

StoryMill is unique in that it has a timeline function that gives authors a way to arrange the scenes in their opus on a graphical timeline. For continuity of the story line, that's a great tool, and it's something that seems to be available only with StoryMill. The package also has a distraction-free writing mode for churning out your average of 1,667 words per day, as well as a Progress Meter for counting down those 50,000 words in your NaNoWriMo novel.

If you're not sure that StoryMill will work for you, there's also a 30-launch free trial that may see you through NaNoWriMo. I'm hoping that all of you TUAW readers who are thinking of writing during NaNoWriMo have signed up by now and have decided what your story is all about. Good luck, and happy writing!
