Blake, or the Huts of America by Martin Delany

This book tells the story of Henry Blake, who was illegally enslaved, but eventually ran away to freedom and to begin agitating slave revolt both in the United States and Cuba. The book was published serially in 1861 and 1862 in two magazines, and the last several issues have been lost, so the ending is in flux. The story moves very quickly from place to place, and highlights as much of Blake's work in fomenting revolt as it does the sentimental story of his wife being sold away from him (and his eventual, successful efforts to win her back). There's a lot of poetry that emphasizes the emotions the enslaved people feel throughout the text.
