I struggled through American Gods. Quite a challenge since my area of expertise has always been Greek/Roman mythology. Don't know a lot of those northern European mythical gods...Thor and Odin, maybe, or African myths. Otherwise ???????? Interesting premise, I suppose, ....won several awards...Hugo Award and Nebula Award for science fiction and fantasy works.
Copied from Wikipedia.....
The central premise of the novel is that gods and mythological creatures exist because people believe in them. Immigrants to the United States brought with them dwarves, elves, leprechauns, and other spirits and gods. However, the power of these mythological beings has diminished as people's beliefs wane. New gods have arisen, reflecting America's obsessions with media, celebrity, technology, and drugs, among others.
Not a favorite though I did like a few quotes
".....elf-light, a thick warm custardly lught that made the world feel unearthly and more than real..."
"Ice sheathed the winter-black bushes and trees as if they'd been insulated, made into dreams."
