The Vanishing Half

What a compelling plot. 1968. Two identical twin sisters. They grow up in a small, light-skinned black community. They leave together to live in New Orleans. One sister, on impulse, decides to apply for a job open only to whites. She gets the job. She passes for white. She never goes back. The other sister marries a dark black man. He beats her. She returns to her black community.

There's lots more, with children, with life experiences for each.

This book would be so good for a book group discussion.
