The vanishing woman

"In 1848, Ellen Craft became invisible. Ellen, a slave from Macon, Georgia, took trains and steamboats north, but the people all around couldn't see her. They saw only a white man. Ellen Craft's mother was a slave, but her father was her master, and she had skin as white as his. So she posed as a white man, while her husband William posed as her slave. Ellen vanished, and she became William Johnson - an ailing gentleman seeking medical treatment in Philadelphia. The Vanishing Woman is based on a true story - one of the boldest escapes in American history. It was an escape driven by prayer, audacity, and the desire for family. William and Ellen knew they could never have children until they were free, so they embarked on the greatest of escapes, running a thousand miles to freedom."--P. [4] of cover.
