Reddit reviews Plainsong

Plainsong by Deborah Grabien. I've never encountered anyone else who has heard of it but it's one of my favorites. It's a post-apocalyptic novel about religion, has talking animals, and is totally charming. It's kind of hard to explain but it's really good, especially if you're into theology or history.

Here's the amazon link with a short summary, it can be bought for $0.01 + shipping. I really recommend it! It's a quick read but worth it.
