If you want a simple and fairly straightforward crash course into Norse mythology, this is possibly the easiest way to have one. It's a story about WWII intertwined with the mythology. I enjoyed the parts about the war, the little glimpses and thoughts of what was going on and how hard it is to comprehend something like a war. The mythology is interesting, but when you're familiar with it, it mostly felt like rereading something you read earlier. I did like how the end of the gods and the end of the war were something like two sides of the same coin. It's a nice and fast read, but not as stunning and intriguing as I hoped it to be.
