The book follows a more concise and informative vein which allows you to lear lots of key elements of the Norse mythology in a short time. Would recommend for basic reading over the subject. Well written as it flows pretty well. At last I would like to mention the great addition of the verses of the Eddas.
It makes for a good general overview, which I think is the purpose of the book. Would have liked a bit more stuff on the gods and rituals, but I understand it would perhaps require a more in-depth book and this is meant more as an introduction.
