Good book suggestions? (i’m an extremely picky reader)

Hellooo I am looking for a book that would fit nicely to me reading it in nature! I am going on a family trip and want a nice and easy read!!
I hate unreal stories and situations (i can’t stand books about flying dragons, harry potter, aliens or anything of that sort im sorry)
i’m not a big book reader as i struggle reading with my adhd so i have no idea what i’d like at this point. i’ve read the “wild swans” recently, it was an easy read and i enjoyed it!
i also do not want it to be a romantic book or solely a comedic book! and no popular books please 😖

something maybe about one’s life or a detective story that isn’t too gruesome? something either nice and relaxing, wholesome or something interesting with suspense 🙂

i’d really appreciate one’s input on this and suggestions!! 😙🙏
