That's Right, NaNos: Lust.

Remeber your main character has to want something. Lust for something.

Sure, it can be a man, woman, what-have-you in a sexual sense, but lust can also refer to power, money, objects, etc. Lust is also a nice reminder that the best verbs really grab a reader.

Hop over to Nossa Morte when you have a spare moment and read "Tesoro's Magic Bullet". And have a great writing day.
