***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**
