First, a caveat. I’m a (lapsed) historian; for me, reading historical fantasies and alternate histories unavoidably sets of alarm bells in the positivist/materialist corners of my brain. That’s largely my problem, not the genre’s. Mary Robinette Kowal’s new novel, Ghost Talkers (Tor, August 2016), her first since wrapping up her five-volume Glamourist Histories, is, like that earlier series, a historical fantasy, and an engaging and readable one at that. But the fact that it’s a historical fantasy set during the Great War, which was one of my areas of focus during my studies, means that I brought more than the usual baggage to this book when I read it. My take on it is more complicated than the typical reader’s would be.
Ghost Talkers is powered by a clever premise. Spiritualism, the craze that swept the western world in the late 19th and early 20th centuries, is real and has been put to use by the British Army on the front lines of the Great War. Their soldiers are conditioned so that when they die, their ghosts report in to teams of mediums, providing valuable intelligence from the front lines. (One imagines suicide missions for intelligence reasons becoming increasingly acceptable.) Ghost Talkers’ protagonist is Ginger Stuyvesant, an American medium working for the British Army’s Spirit Corps, a secret wing of the army’s intelligence services. Her work, and those of the other mediums, is overwhelming: the toll of the dead is relentless, and Ginger, like other mediums, runs the risk of having her soul separated from her body.
