The Secret History of Science Fiction is the third Tachyon anthology edited by John Kessel and me.   It came out in the fall and has been selling fairly well, according to our publisher.  But we have taken a lot of flack for it, mostly for the introductory essay.   Here's how it starts:

In 1998, the Village Voice published an essay by Jonathan Lethem titled “Close Encounters: The Squandered Promise of Science Fiction” which begins with an alternative history in which Thomas Pynchon’s Gravity’s Rainbow was voted the 1973 Nebula Award by the Science Fiction Writers of America. In fact, though Pynchon’s landmark work of postmodern fiction was indeed nominated for the Nebula that year, the award went to Arthur C. Clarke’s Rendezvous with Rama. Lethem called this moment “a tombstone marking the death of the hope that science fiction was about to merge with the mainstream.” 

and later in the introduction we write:

We understand why some might say that, after the mid-1970s, sf went back to the playroom, never to be taken seriously again. But they do a vastdisservice to the writers and readers of the next thirty years. What we hope to present in this anthology is an alternative vision of sf from the early 1970sto the present, one in which it becomes evident that the literary potential of sf was not squandered. We offer evidence that the developments of the 1960s andearly ’70s have been carried forth, if mostly outside of the public eye. For years they have been overshadowed by popular media sf and best-selling books thatcater to the media audience. And at the same time that, on one side of the genre divide, sf was being written at the highest levels of ambition, on the other side,writers came to use the materials of sf for their own purposes, writing fiction that is clearly science fiction, but not identified by that name.

This is the secret history of science fiction.

Because of our thesis, that the genre divide is more apparent than real, our critics have charged that we don't really understand science fiction.  Guilty as charged.  One of our chief arguments is that the term science fiction has lost all definitional rigor, and that science fiction has as many flavors as Crayola has crayons, and that many of these "flavors" point toward a convergence with the literary mainstream.

At any rate, we get another chance to make our case in an upcoming interview in the literary journal Rain Taxi.  Stay tuned!  In the meantime, here are links to some of the reviews:
