Great Refference, not-so-great tutorial
This is a great reference for just about anything you want to know about manga, from supplies to types of manga to advice on how to get works published. The only downside is a little big, however--i found the actual tutorials on how to draw manga difficult to follow. The book is great for looking up quick questions about how to draw eyes, for example. But if you want a step-by-step walkthrough on drawing a manga character, this isn't the right book.
