"Quentin Coldwater has been cast out of Fillory, the secret magical land of his childhood dreams. With nothing left to lose he returns to where his story began, the Brakebills Preparatory College of Magic. But he can't hide from his past, and it's not long before it comes looking for him. Along with Plum, a brilliant young undergraduate with a dark secret of her own, Quentin sets out on a crooked path through a magical demimonde of gray magic and desperate characters. But all roads lead back to Fillory, and his new life takes him to old haunts, like Antarctica, and to buried secrets and old friends he thought were lost forever. He uncovers the key to a sorcery masterwork, 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"--

Quentin and his friends are now the kings and queens of Fillory, but the days and nights of royal luxury are starting to pall. After a morning hunt takes a sinister turn, Quentin and his old friend Julia charter a magical sailing ship and set out on an errand to the wild outer reaches of their kingdom. Their pleasure cruise becomes an adventure when the two are unceremoniously dumped back into the last place Quentin ever wants to see: his parent's house in Chesterton, Massachusetts. And only the black, twisted magic that Julia learned on the streets can save them.
