Write a how-to book, in a vampire edition. Tell how to avoid getting your neck bitten, or how to protect your family from turning. You could even write about how to keep your vampire identity hidden. Take this guide very seriously, it may save a life.

Questions:

What are you teaching? How does this help anyone (vampire or human)? Why do they need to know this? How are you going to divide your guide so readers can better understand it?
