Now eighteen, Cale Holland and Zeb Meadows have been best friends since they were freshmen in high school, and Zeb has been in love with Cale most of that time. While returning to their hometown after a trip to the state capital, Cale realizes his feelings for Zeb are growing beyond friendship, and Zeb is ecstatic to finally have a chance at romance with Cale.
On their trip, Cale is mysteriously drawn into the nearby countryside. He discovers a lake so beautiful, his father buys the surrounding property to build a residential development—despite rumors that the area is haunted—and soon after, Cale and Zeb return to the lake on a weekend camping trip to unwind and explore their feelings for each other.
But the haunting of the lake is more than a rumor. In the process of developing the land, Cale’s father accidentally frees an invisible entity that feeds on the energy of living creatures… and Cale and Zeb find themselves in a fight for their lives as they are stalked by the soul-devouring Haint.
