The Book of the New Sun is unanimously acclaimed as Gene Wolfe's most remarkable work, hailed as "a masterpiece of science fantasy comparable in importance to the major works of Tolkien and Lewis" by Publishers Weekly, and "one of the most ambitious works of speculative fiction in the twentieth century" by The Magazine of Fantasy and Science Fiction. Sword & Citadel brings together the final two books of the tetralogy in one volume:

The Sword of the Lictor is the third volume in Wolfe's remarkable epic, chronicling the odyssey of the wandering pilgrim called Severian, driven by a powerful and unfathomable destiny, as he carries out a dark mission far from his home.

The Citadel of the Autarch brings The Book of the New Sun to its harrowing conclusion, as Severian clashes in a final reckoning with the dread Autarch, fulfilling an ancient prophecy that will forever alter the realm known as Urth.
