Magical realism is an infusion of magical into reality, hence the term. It's usage lends itself to the awe and wonder of a woman that freed many enslaved during a terrible time in US history. It's not a literary device everyone will enjoy, but it is such an intriguing way to explore Harriet Tubman. I love reading Coates for his ability to infuse this real world and its troubles into his fictional works. Highly recommend this incredible book.
