From Piers Anthony: "I stopped writing the fifth Geodyssey novel, Climate of Change, at 112,000 words, or about two thirds through, when I lost my market for the series. Critics who blame me for writing light fantasy evidently haven't tried the market for serious history. But I have to say that the novel was not shaping up to my expectation. So while there is material there I'm sorry to lose, such as a chapter set in Beringia, the land between Alaska and Sibera 20,000 years ago, I am not at all sure I'll ever complete the book. Still, I don't like to leave things unfinished, so if I live long enough and the market changes, I may yet return to it."

More from Piers: "The title of my unfinished fifth Geodyssey novel is Climate of Change ... That series is now on hold—loss of market—but I’ll continue to research as convenient, awaiting the time when readers get more interested in historical fiction than in fantasy, or when some fluke makes me famous enough to sell substance again instead of fluff. Critics who condemn me for the latter have no idea of the nature of the commercial market. If eventually I get tired of waiting I’ll finish it and self-publish it at Xlibris."
