What to read after This Strange New Feeling?

Two short stories and one novella (all based on true stories) about love in the time of slavery. The first is about Ras, who helps other slaves escape, and ultimately escapes with his girlfriend, Sally. The second is about Maria, whose husband (a free black man) buys her but neglects to officially set her free; when he dies, she finds herself a slave again because her husband had debts and so she becomes the payment. The third is about William and Ellen Craft, a famous slave couple who escaped by pretending that Ellen (with her very light skin) was a white woman being escorted north by her slave; they went on to speak against slavery form the home base of Boston.
