Gene Wolfe's BOOK OF THE NEW SUN has been hailed by both critics and readers as quite possibly the best science fiction novel ever written. And yet at the same time, like another masterpiece of fiction, James Joyce's Ulysses, it's been deemed endlessly complex and filled with impenetrable mysteries. Now, however, in the first book-length investigation of Wolfe's literary puzzlebox, Robert Borski takes you inside the twisting corridors of the tetralogy and along the way reveals his solutions to many of the novel's conundrums and riddles, such as who really is Severian's lost twin sister (almost certainly not who you think) and why he believes the novel's main character may not even be the torturer Severian. Furthermore, and in essay after essay, Borski demonstrates how a single master key will unlock many of the book's secret relationships--all in the attempt to guide you through the labyrinth that is Gene Wolfe's BOOK OF THE NEW SUN.
