At an Antarctic research station in the 1980s, two men at their end of their respective tethers, alone in this lovely if unlovable land but for one another and a copy of Emmanuel Kant’s Critique of Pure Reason, see something that cannot conceivably be:
There was a hint of—I’m going to say, claws, jaws, a clamping something. A maw. Not a tentacle, nothing so defined. Nor was it a darkness. It made a low, thrumming, chiming noise, like a muffled bell sounding underground, ding-ding, ding-ding. But this was not a sound-wave sort of sound. This was not a propagating expanding sphere of agitated air particles. It was a pulse in the mind. It was a shudder of the soul.
Sound familiar? Well, it is—for a fraction of a chapter.
