The Tent by Kyle Couch

5.10

An apocalyptic event known as The Crisis has devastated David's world leaving him to rely on survival tactics learned from childhood. Isolated and alone, David has taken refuge in a tent on the edge of the wilderness. Soon enough, another survivor emerges, Mary, who immediately begins questioning David's tactics and ultimately putting them in the cross-hairs of "Those Who Walk In Darkness", unseen creatures that may or may not be responsible for The Crisis.
