I rated this book 10 because it was excellent! It is about a girl who finds out that her parents aren't her real parents because on the day she was born so were 5 other little babies. One of the babies name was Marlene. In the book Marlene gets hit by a van and her parents try to donate blood but it didn't work and that is when they found out that Marlene wasn't there daughter and they suspect that Susan is. Now the family wants Susan to live with them since she is there real daughter but Susan wants to live with the family she has always known.
