This novel has an incredibly strong voice; it is written as if by Celie herself, an uneducated young woman, which brings you closer to the character though it is sometimes difficult to see exactly what is happening, both to the other characters and to her. It seems much more real because of this; there's no all seeing eye.
The narrative itself is difficult, Celie suffers every kind of abuse throughout her life and the other female characters don't fare so much better. The beacon throughout the book is the relationships Celie forms with the other female characters. Even if there are some rocky starts and tensions they lift up and support each other. It feels important.
