I am looking for a books name which I've read,
I'm hoping someone can help please.It's about a girl which best friend has gone missing, then she goes looking for her,at this rich guys place, where she knew her friend was. She than falls in love with this guy,
Long story short, her best friend comes back in the end, of book one,
