A collection of Random yet precise prompts - some inspired by other challenges.  Colors, book length, moods, recommendations - a hodge podge.  Physical, digital and audiobooks all count.  I'm not here to crimp your style.  There are a couple of incidental prompts - you don't necessarily pick a book for it, but as your reading through your TBR lists things happen - you laugh, you cry, you think "so-and-so would love this".  I'm not going to say you can't add a book to multiple lists, but the idea is a different book on each list.
