Query: I really like this book

Christopher Hart's book manga mania fantasy worlds is awsome! The book has alot of characters for different genres that would be helpful in giving your characters a special ability and a sense of personality with each power/ability. I love how the book has difference in each race, and gives you a variety of worlds. This book is a must have for those seeking to create a manga in a certain genre background and for ideas of what kind of race they would want their character to be.
