Amos Fortune was born At-mun, the son of a king in Africa. Before he knew it, he was seized and taken to America, to be sold as a slave. He was fortunate, however, and was sold to a kind Quaker who treated him justly and beneficently and allowed him to buy his freedom. All his life (and he lived a long life, living to nearly one hundred) Amos helped others become free, including all three of his wives.
With a copyright date of 1950, I anticipated there would be lots of racist elements to this book. There were, but the book was redeemed somewhat by the depiction of Amos as a pioneer, a good man, a man who led the way for others.
