Caitlín R. Kiernan’s second novel doesn’t read like a sophomore effort. Threshold is a careful, subtle descent from normal day-to-day life in Birmingham, Alabama, into a bottomless, lightless reality where the laws of nature we hold to be inviolable are as flimsy as balsa wood.
Three years ago, protagonist Chance Matthews, her then boyfriend Deacon Silvey, and her friend Elise got stoned, and for a lark, broke into Birmingham’s water works, situated deep in Red Mountain. What happened there is a black hole in Chance’s memory, but she has more important concerns. Days after Elise commits suicide, Chance’s grandfather suffers a fatal heart attack, leaving her alone in their family home at the top of Red Mountain. A hard-headed Invertebrate Paleontologist, just like her late grandmother, Esther Matthews, she is not prepared for teenage albino runaway, Dancy Flammarion. After all, Chance is still deep in the throes of grief when the girl waylays her in the library, apparently knowing that they would meet in that very place, at that very moment, even though Dancy has just arrived in town from the swamps of Florida.
Desperate to convince Chance that they have something important to do, she also drags Deacon and his current girlfriend, Sadie Jasper, into her very strange orbit. Once the four are together, Dancy reveals her urgent secret: she can see monsters, she hunts and kills them, and she has a small jar with a severed finger in solution to prove it.
Despite their skepticism, Dancy unerringly leads the three to an unmarked crate in Chance’s own house. The contents are the final, unfinished work of Esther Matthews: a journal, a piece of hematite with an impossibility embedded in it, and a small bottle with a sample of something indescribable. As Chance investigates these things, something awakens in Birmingham, something that will do absolutely anything to keep the crate, the history of Chance’s family, and all four of these investigators silent. Forever.
Caitlín Kiernan takes us on a five-hundred-million year odyssey through deep time, and gradually, with dreadful precision, tumbles us into a horror older than man, older than the great saurians that once walked the Earth.
Threshold is a work of Lovecraftian, cosmic proportions, and Caitlín Kiernan is already a master of the supernatural with this second novel.
