Until Death Do Us Part

Abigail is a normal 14 year old girl who lives in a foster home. The only thing that isn't normal is that she has been able to see ghosts since she was 7 years old. She tells her best friend Josie about it and then Josie tells the head of the foster home who tries to put Abigail into a mental hospital. (Sorry if the book isn't that good it is my first book)
