It's your book's identity, all rolled up into a few simple words. Your book title is the shortest part you'll write, but it may be the most important few words you'll create. Imagine if you'd read Rhett & Scarlet and Rabbits Finding a Home instead of Gone With the Wind and Watership Down. They'd probably be a bit less memorable, less magical. A good title sets the stage and gives readers a hook on which to hang their emotions. Your perfect title can come from the most surprising of places.
