What would you read!?

If you could choose a book genre, theme, type.. What would you read?
Horror, comedy, life story, fiction, science fiction,, factual, crime thriller or something else?
How long would it have to be?
War and piece or a good short story?

Yes this blog entry is a bit of market research but it can help me target the next couple of books.

I have a few ideas but want to see what I should be considering.

Thanks for the help in advance
