Lava Red Feather Blue if it had AO3 tags

(If you don't know what AO3 is and/or don't like fanfic, you'd best skip this one.)

I've seen people say that they'd love to have AO3-style tags for novels. As a longtime fandom person, I concur! So, for fun, here is what the listing for Lava Red Feather Blue might look like if it were a fic on AO3. For now, I chose from tags that actually exist there, rather than inventing my own (although inventing one's own tags is very AO3). Feel free to suggest more if you've read the book! 🙂

… What do you think? Would it be helpful if books had tags like these to tip you off as to the contents, or do you like as few spoilers as possible?
