Yea the DVD is cool, the book is more of a "Coffee Table Book" while it gives you information about the pictures it displays its basic and is geared toward making people aware of the dangers the coral reefs face and displaying their beauty at the same time.
The Conscientious Marine Aquarist, by Robert M. Fenner IMO is probably the best guide to beginner and intermediate reef keeping you can get. IMO a must have for anybody new to the hobby.
