"A mysterious and deeply relevant book . . . Superb." Mariana Enriquez, author of THE DANGERS OF SMOKING IN BED
"Hypnotic [and] filled with tension . . . Masterful." Samanta Schweblin, author of FEVER DREAM
Something alive and unclassifiable has been coursing through the Earth since its creation, and seems capable of outliving it.

It spreads beneath the surface; a mysterious organism that moves unlike any other, stretching for miles and emitting strange sounds, drawing unsuspecting victims toward it.

Through history it appears at moments of great and terrible consequence: in 1504, as Spanish conquistadors first encounter the Mapuche people; in 1888, as London is rocked by the violence of Jack the Ripper and seismic technological advances; in 1945, as the world tears itself apart in war... and in 2036, in a fragmented, unsettling future.

Time and again, as human evolution fuels itself on its own horrifying idea of progress, and brutality reaches boiling point, the organism emerges. Witnessing. Sheltering. Consuming.
