Tor Essentials presents new editions of science fiction and fantasy titles of proven merit and lasting value, each volume introduced by an appropriate literary figure. Far from Earth, two sister planets, Saint Anne and Saint Croix, circle each other in an eternal dance. It is said a race of shapeshifters once lived here, only to perish when men came. But one man believes they can still be found, somewhere in back of the beyond. In The Fifth Head of Cerberus, Gene Wolfe skillfully interweaves three bizarre tales to create a mesmerizing pattern: the harrowing account of the son of a mad genius who discovers his hideous heritage; a young man's mythic dreamquest for his darker half; and the bizarre chronicle of a scientist's nightmarish imprisonment. Like an intricate, braided knot, the pattern at last unfolds to reveal astonishing truths about this strange and savage alien landscape. With a new introduction by O. Henry Award winning author Brian Evenson
