I agree with Tammy Host-- this photog seemed sketchy from the get-go and despite everyone's warnings, you decided to go with him anyhow. And now you're upset that he's not moving mountains for free and are expecting us to side with you.
I think it's time for you to own this bad decision and move on. If you get your book, then great but without a contract or payment then there is nothing to go on. You put six hours of time into it but if he is legit, it will take him much much longer to work on the photos and then make a book from them. If you want a book so badly, why don't you use a service like blurb.com and make it yourself?
