The air is crisp, the leaves are changing, and soon enough we'll be dusting off our coziest sweaters and sipping apple cider - let's read some spooky books!
Horrors, thrillers, and mysteries are perfect for this chilling season, though if you have a dark fantasy or an autumnal romance or literally anything you feel fits a prompt, go for it! Also, if you enjoy non-fiction, feel free to read a book about the prompt topic instead (e.g. horror in 80s, the history of vampires in literature, etc.). The only "rules" would be to find up to 13 unique books that have autumnal vibes, read in prompt order. 
There are twelve prompts, plus a bonus one, so this should come out to four books a month for the whole season, or close to one book a week. Take your time, enjoy the magic of Autumn, and, of course, have fun!
