Shatterday is a revolutionary classic from Harlan Ellison, science fiction's most controversial author. This collection of sixteen visionary stories remains as scathing and influential today as when it was initially published. Read as fanatically by intellectuals as by college students, these category-defying stories combine ironic humor, sardonic social criticism, and intense self-revelation; from ?Jeffty Is Five," the tragedy of an innocent child wrenched out of an idyllic past, to humanity's encounter with dangerously seductive aliens in ?How's the Night Life on Cissalda?", culminating in ?Shatterday," the dark allegory of an identity-stealing doppelganger replacing his inferior twin. Back in print for the first time since its stunning debut in the early 1980s, this incendiary collection reestablishes its legendary author at the cutting-edge of the short-story form.
