Ad lit.org: Reading Discussion Guide: The Winter Knights

As the floating city of Sanctaphrax becomes gripped by a harsh and relentless winter, Quint begins his training in the Knights Academy, the venerable school charged with training the elite band of Knights Academic. As the buoyant rock cools and expands to the point of ripping free of its anchor chain, the city's hierarchy and power structure is threatened by internal forces and bitter rivalries. It's up to Quint, and his band of Winter Knights, to save Sanctaphrax from a coup that will surely end life in Sanctaphrax as he knows it, before time runs out for good.
