Don't awaken what sleeps in the dark.

In a future ravaged by fire and drought, two climate refugees ride their motorcycles across the wasteland of the western US, and stumble upon an old silver mine. Descending into the cool darkness of the caved-in tunnels in desperate search of water, the two women find Lavinia Cain's diary, a settler in search of prosperity who brought her family to Nevada in the late 1860s.

But Lavinia and the settlers of the Western town discovered something monstrous that dwells in the depths of the mine, something that does not want greedy prospectors disturbing the earth. Whispers of curses and phantom figures haunt the diary, and now, over 150 years later, trapped and injured in the abandoned mine, the women discover they're not alone... with no easy way out.

The monsters are still here—and they're thirsty.
