For YA specifically, I’m still angry that Code Name Verity by Elizabeth Wein wasn’t a bigger hit-- WW2 epistolary novel about teen girls in the RAF and being captured by Nazis. I sobbed through this book and haven’t stopped talking about it since.

I read all 14 or 15 or whatever Wheel of Time books and the one thing that upset me the most was an animal death in the last book! Animals don’t have any responsibility for the terrible human situations they get pulled into.
