Sawyer Books, 2008) begins with a 17,000-word essay by her describing the movement and its practitioners, and collects stories by Gregory Frost, James Patrick Kelly, John Kessel, Jonathan Lethem, James Morrow, Kim Stanley Robinson, Robert J. Sawyer, Tim Sullivan, and Connie Willis, with introductions to each by Kelleghan.[5] That essay, "A Definition of Savage Humanism, with Autobiographical Anecdotes," is reprinted as the cover story in the November 2008 edition of The New York Review of Science Fiction, and takes up most of that issue of the magazine.
