The Algonquin Falls grand opening proves deadly when creatures of myth emerge from below and begin slaughtering every man, woman and child. Trying to avoid being killed and eaten, Jesse and his group have no choice but to enter the expansive cave system under their feet and search for alternate means to escape the state park. Soon they meet up with Charly and her band of survivors that are on a rescue mission, and together they join forces where not only are they outnumbered, but something much larger, more powerful, is also on their trail.
Salem Hawley may be a free man after the American Revolution, but his troubles are plenty. A good friend seeks his help, turning Salem's attention to the graves being emptied and the deceased experimented upon and studied by medical students and physicians. It goes ignored, yet Salem is determined to do something, anything. If only he knew about the rituals being performed, the Old Ones being worshiped, right under his nose. If only he knew that New York City is on the cusp of ruin.
