Every ninetieth solar eclipse, a portal tears open between the demon realm and our world, and each time it appears at a different crypt. This eclipse it has surfaced deep in the desert, inside the ancient pyramids of the damned. Trained Crypt Stalkers are the only line of defense against what pours through, and this time the assignment falls to Gladys, a descendant of that storied lineage, who must close the portal before the demons can run free.
