I have been looking for this book for a while, came across this email on twitter and thought I would ask! All I remember is it is about a girl and a boy, the book is told from both perspectives, the girl is a poor girl who has a chicken coop/chickens in her backyard, and is from a poorer family. I believe she just moved into the area, and her neighbor is a boy from a more well off family who initially is embarrassed by her and she had a crush on him (I’m not sure if his parents made him be friends with her because she was new to the area). Eventually as the story progresses and they get older the roles essentially switch where she becomes very pretty and popular and eventually moves on from liking him due to him being mean to her and her realizing her worth while he then begins to develop feelings for her. That’s pretty much the gist of what I remember and would love any help in finding the name of the book. I also want to say the cover was pink and blue (or had those colors on it)
