As the title says, Found Family is by far one of my favourite tropes, and I'd love to find some new books using this trope. Any genre is fine; I don't mind if it's fiction or nonfiction. The characters also don't have to be in the same age group. (Some of the best found families I've read include found parents/grandparents, etc.)
Some of my favourite books include Vicious by V.E. Schwab and Britt-Marie Was Here by Fredrik Backman.
