In 1973 celebrated writer and editor Harlan Ellison announced the third and final volume of his unprecedented anthology series, which began with Dangerous Visions and continued with Again, Dangerous Visions. But for reasons undisclosed, The Last Dangerous Visions was never completed.

Now, six years after Ellison's passing, science fiction's most famous unpublished book is here. And with it, the heartbreaking true story of the troubled genius behind it.

Provocative and controversial, socially conscious and politically charged, wildly imaginative yet deeply grounded, the thirty-two never-before-published stories, essays, and poems in The Last Dangerous Visions stand as a testament to Ellison's lifelong pursuit of art, uniting a diverse range of sci-fi writers both famous and newly minted, including: Max Brooks, Edward Bryant, Cecil Castellucci, James S. A. Corey, Howard Fast, Patricia Hodgell, Dan Simmons, Robert Sheckley, Adrian Tchaikovsky, Mildred Downey Broxon, and Cory Doctorow, among others.

With an introductory essay by J. Michael Straczynski entitled "Ellison Exegesis," the historic publication of The Last Dangerous Visions completes the long-awaited final chapter in an incredible literary legacy.
