Working on a book

OK.... I am determined to write a book, and I have a few ideas. This is the one I'm working with the most, call it my baby. Its a tell all form the Devil herself (yes in my book the devil is a woman) now its not set to be "funny" purse, its set more as her telling the world what REALLY went down and how things have transpired form her point of view. What do you think???
