"A poetic, doom-laden Western soaked in blood and frenzy. This Cormac McCarthyesque terror fantasia of a prequel both frames and outstrips Hoover's Haxan" (Gemma Files, author of Spectral Evidence).

Before he became a US federal marshal in Haxan, John Marwood rode with a band of killers up and down the Texas-Mexico border. Led by Abram Botis, an apostate from the Old Country, this gang of thirteen killers searches for the fabled golden city of Cibola, even riding through the barren, blood-soaked plains of Comancheria. In this violent crucible of blood, dust, and wind, Marwood discovers a nightmarish truth about himself, and conquers the silent, wintry thing coiled inside him.
"After 2014's brilliantly brutal Haxan, Hoover revisits his nightmarish American West . . . A western of blood and violence with a marked lack of redemption tinged with hints of the fantastic, this is a pitch-black western that resonates." —Publishers Weekly
"With a voice both sparse and poetic, Hoover takes on the hoary cliches of Western fiction and dismantles them one by one. In Quaternity, Hoover's unflinching look at evil will challenge everything you know about yourself and the world we live in." —Melissa Lenhardt, author of Heresy

"Hoover does it again. Quaternity starts with a bang and doesn't quit until a satisfying conclusion. This is my kind of weird west. Love it!" —Jennifer Brozek, author of The Last Days of Salton Academy
