Grade 7-10-The intense, personal slave narrative of 14-year-old Forty-seven becomes allegorical when a mysterious runaway slave shows up at the Corinthian Plantation. Tall John, who believes there are no masters and no slaves, and who carries a yellow carpet bag of magical healing potions and futuristic devices, is both an inspiration and an enigma. He claims he has crossed galaxies and centuries and arrived by Sun Ship on Earth in 1832 to find the one chosen to continue the fight against the evil Calash. The brutal white overseer and the cruel slave owner are disguised Calash who must be defeated. Tall John inserts himself into Forty-seven's daily life and gradually cedes to him immortality and the power, confidence, and courage to confront the Calash to break the chains of slavery. With confidence, determination, and craft, Tall John becomes Forty-seven's alter ego, challenging him and inspiring him to see beyond slavery and fight for freedom. Time travel, shape-shifting, and intergalactic conflict add unusual, provocative elements to this story. And yet, well-drawn characters; lively dialogue filled with gritty, regional dialect; vivid descriptions; and poignant reflections ground it in harsh reality. Older readers will find the blend of realism, escapism, and science fiction intriguing
