u/Kestrelpond

I remember her name was Birdie or something similar, and the book starts with a very gruesome scene where she has to >!kill her grandma's cat!< (tw for animal cruelty mentioned), she also is going through puberty and >!Her 5th? Grade teacher assaults her and another girl on a field trip!< (tw for SA)

I also remember details about a specific war being mentioned, but I know they had radios/TVs, and cars of course. Any help would be greatly appreciated I cannot for the life of me remember the name
