D'Aulaires' Book of Norse Myths

I loved the D'Aulaires' Book of Greek Myths so much that I bought a copy of their Norse Myths book at BookExpo.

I liked Norse Myths a lot, but...not as much as Greek Myths.

Why?

The creatures in the Norse myths are not familiar to me. I had to keep looking up the definition of “jotun” and “Aesir god” and “fire demon” and I couldn't remember how they ranked with each other. I also was not familiar with the Norse mythological gods and I kept having to look up who “Loki” and other creatures are and how they related to each other.
