Cannot talk about a book.
The so-called Nordic mythology refers to the original beliefs of the ancient Scandinavians or the so-called Norsemen, and their heroic legends are also included. Regarding the earliest and most important transmitter and embellishment of this part of the myth (we should not forget that the myths passed down to this day have been continuously modified by unknown poets), scholars have two opinions: one is that The ancient poets of Norway, because the customs, laws, and objects described in the Elder Edda or Poetic Edda, which preserved most of the mythological materials, seem to belong to the south. Norway; the other is the ancient Skald poets from Iceland, because it is generally recognized that until the fourteenth century, the Icelandic Skald poets were still very important to the development of Nordic literature, and it is said that they edited Saemund (1056-1133), who wrote the Great Edda, also collected material from Iceland.
The "Great Edda" is the most important ancient book that preserves Norse mythology. The story of Balder, the god of light, the story of Skirnir's journey, and the story of Thor's hammer, are all in the Great Edda. Of particular importance are the twelve poems about the Nibelung story, from which the famous Germanic poem "Nibelungenlied" was born. In addition to the "Big Edda", there is also the "Younger Edda" (Younger Edda), which is also called the "Prose Edda" because it is written in prose.
I have never seen a systematic Norse mythology in the bookstore. You can find "Norse Mythology ABC" online. However, this book also introduces Norse mythology in a concise way. I quoted the two sentences above from it.
Some domestic books about Nordic mythology include "The Song of the Nibelungs", People's Literature Publishing House
"Norse Mythology and Heroic Legends", Contemporary World Publishing House
