Shusterman once again wields his magic in this chilling sequel to Scythe (2016) and delves into the inner workings of the Thunderhead, the all-powerful and omniscient artificial intelligence that rules the world. A year has passed since Rowan went off the grid. He’s now become an urban legend and is living the life of a vigilante, taking the lives of the corrupt scythes who kill for pleasure or for personal gain. Meanwhile, Citra, now the ordained Scythe Anastasia, openly challenges the status quo and opposes the homicidal "new-order" scythes and their dangerous demagogue. As Rowan and Citra find themselves on opposite sides will the Thunderhead break its own laws and intervene or will it simply watch as this perfect world begins to unravel?
