This is the first-person narrative of Severian, a lowly apprentice torturer blessed and cursed with a photographic memory, whose travels lead him through the marvels of far-future Urth, and who--as revealed near the beginning--eventually becomes his land's sole ruler or Autarch. On the surface it's a colorful story with all the classic ingredients: growing up, adventure, sex, betrayal, murder, exile, battle, monsters, and mysteries to be solved. (Only well into book 2 do we realize what saved Severian's life in chapter 1.) For lovers of literary allusions, they are plenty here: a Dickensian cemetery scene, a torture-engine from Kafka, a wonderful library out of Borges, and familiar fables changed by eons of retelling. Wolfe evokes a chilly sense of time's vastness, with an age-old, much-restored painting of a golden-visored "knight," really an astronaut standing on the moon, and an ancient citadel of metal towers, actually grounded spacecraft. Even the sun is senile and dying, and so Urth needs a new sun.
