Clotel [EPUB ebook] 
or, The President’s Daughter

This novel explores slavery’s destructive effects on African-American families, the difficult lives of American mulattoes or mixed-race people, and the ‘degraded and immoral condition of the relation of master and slave in the United States of America.’ It is a tragic mulatto story about a woman named Currer and her daughters Althesa and Clotel, fathered by Thomas Jefferson.
