A gifted young knight named Collum arrives at Camelot to compete for a spot on the Round Table, only to find that he’s too late. The king died two weeks ago at the Battle of Camlann, leaving no heir, and only a handful of the knights of the Round Table survive. They’re joined by Nimue, who was Merlin’s apprentice until she turned on him and buried him under a hill. Together this ragtag fellowship will set out to rebuild Camelot in a world that has lost its balance. But Arthur’s death has revealed Britain’s fault lines. Kingdoms are turning on each other, warlords lay siege to Camelot, and rival factions are forming around the disgraced Lancelot and the fallen Queen Guinevere. It is up to Collum and his companions to reclaim Excalibur, solve the mysteries of this ruined world and make it whole again.

Quentin Coldwater has been cast out of Fillory, the secret magical land of his childhood dreams. But he can’t hide from his past, and it’s not long before it comes looking for him. He uncovers a spell that could create magical utopia, a new Fillory --- but casting it will set in motion a chain of events that will bring Earth and Fillory crashing together. To save them, he will have to risk sacrificing everything.

In this sequel to THE MAGICIANS, Quentin and his friends are now kings and queens of Fillory, but a life of royal luxury goes wrong when a magical ship brings Quentin back to his parents' house in New England.
