After looking through this book I can understand why some images were banned in certain places. This series is probably some of the most risque work Royo has done or at least that I've come across. It's till beautiful art but I'd recommend it only for the die hard fans and then even if you are a die hard have an open mind. If you're not a die hard fan but are interested in Luis Royo and want to check out his books I recommend perhaps starting with one of his earlier series because this one could possibly turn you off.
In saying that I still loved it myself and want to get the whole series now.
