The Einstein Intersection

Samuel R. Delany · Ace Books · 1967

True first is the Ace paperback original of 1967 (F-427). The Victor Gollancz UK hardcover of 1968 is later and notably restores a chapter that the Ace text omits, but the Ace paperback remains the true first edition. Won the 1967 Nebula Award for Best Novel, tied with Daniel Keyes's Flowers for Algernon.
