Some advice. It's seldom a good idea to talk with anyone about something you're writing. There is a power in not speaking about a thing until it is done. If you speak about it, you will be less inclined to actually finish it - and your subconscious mind will work less hard to put it together in the background before you write. In addition, haters will emerge who will discourage you from finishing the book in all kinds of ways. It sounds interesting... but finish it first then talk about it.
