I am in search of a specific novel I remember reading when I was younger. The book must've been written AFTER 2000 and before 2008.
The "protagonist" of sorts is a girl (I can't remember her name), which's mother has passed away. Because of her mother's death, she moves to live with her rich grandmother and her husband.
There might be a friend involved called Kimmi, or something like that.

Thanks in advance

I'm sorry, I made a mistake. The book is written BEFORE 2000 and not after 2000, as written.
