Harriet McCorvey, a high school junior, was raped by her pastor. She later realizes that she's pregnant. The local abortion business, a branch location of Preferred Personhood Foundation, examines her and discovers that she is pregnant with twins and they have a condition known as Trisomy 21, Down Syndrome. The babies are identical twins. Their tissues are priceless in the eyes of some research companies who are trying to produce better tests for Down Syndrome and, possibly, a vaccine. Aunt Thommie's Cabin is the story of a pregnant young girl's efforts to escape from Preferred Personhood and those who have sold her babies to a research company. Harriet, still pregnant, courageously makes her way through a blinding snowstorm, seeking refuge, trying to save her babies, and keep them alive. In 1852, Harriet Beecher Stowe published Uncle Tom's Cabin, a book which stunned Americans with its presentation of the truth about the evils of slavery.
