I read this book in two parts, up to Chapter 12 and then after 12. It was really good and I burned straight through it in two separate chunks. I'm still trying to sort out all the little nuances and I had to go and search for whom some of the gods were but it turned out to be pretty good in the end. I still think I liked the Graveyard book better but this is definitely worth a read.
I've first read this book when I was nineteen. Now, at age 29, it was finally time to read it again and it was every bit as amazing as the first (and second and third) time. Having visited the US many times since I've read this book last, I think I gained an ever deeper understanding for its mythology. Mind blown.
It's taken me a few weeks since I finished American Gods to review it, because I'm not quite sure how much I liked it. Its tone is extremely different from Stardust and Neverwhere; it's very dark, dreary, and cold, and it's difficult to root for any of the characters. No one is entirely sympathetic, although it's not as if any of them have really done anything wrong.
The premise of the novel is that as immigrants came to America, they brought their gods with them, and as America aged, its people no longer had a use for gods and abandoned them. It's fitting that the gods are now bleak and run-down. Shadow, the main character, is recruited by one of these gods to assist in a war against the newer gods - the gods of technology, highways, and the future. These newer gods are especially easy to dislike; they come across as sleazy and creepy.
I think this one is going to need a re-read relatively soon. It's so much deeper than a novel about warring gods, and I think I was ill-prepared for it coming off of Gaiman's lighter fare. There are so many themes running through the plot that I think I might trip over them trying to sort them all out.
Definitely recommended, but approach it expecting more than just a story.
