Query: A Great Book For Diehard Batman Fans

This book is pretty good. It has a greta intirpritation of how bataman came to be and about a young police cop named Gordan. This is great because it shows batman bleeding and not always succeding like in many other books and movies. it shows him learning as he goes along. The thing that dissappointed me was that I felt like this book could of gone on for a couple more pages. it has a great plot but i thought the ending happended to quickly. It's still a great book though and hopefully the next batman movie they make will be based of this book.
