Nonfiction: The Color of Water 1

I know pretty much nothing about this book except that it is about a mixed-race family and a black man who grew up with a white mother. I'm finding it hard to predict anything, not knowing anything about it, but I guess it will probably deal with racism and maybe some violence. It probably takes place in the North, since Southern Jim Crow laws banned interracial marriage. I'm curious as to whether the parents' marriage lasted, or if they divorced or separated because of prejudice around them- the dad was almost certainly black, if the kids are and the mother's white. I wonder if there were some siblings with light skin, and if that caused tension in the household.
