Book Review:"color purple"

I read "Color Purple". This book was told about black people. It was a little bit difficult for me to read and understand. I felt scary and anger. Because the women were always violated by man. Woman have to obey their husband and man all the time, like follower. Woman has been discriminating against for a long time, because they are woman, only this reason.
There were two sisters in this book. They were separated forcibly. They cried and cried. But lastly they met again after an interval of fifty years. It's happy end!!
