HOW TO: Write a Novel Using the Web offers a toolkit for using the web to write a book. Highrise is suggested as a way to track the "lives" of all your characters.
If your story is very character heavy, keeping track of all the people in your novel, who they are, and how they interact will be vital to making sure the continuity isn’t interrupted. It may seem silly to treat your fictional characters as real people, but using an online CRM application like Highrise (which offers a free account good for 250 characters), can be a great way to keep track of the people in your book. Create an entry for each character and treat them like real people, attaching notes about their interactions, histories, and characteristics as you write.
