After the death of his mother, twelve-year-old Ethan moves to his grandmother's house in a small town in Maine. He barely knows her, the house feels unsettling, and strange things begin to happen almost immediately. As Ethan struggles to adjust, terror strikes the town. An unknown, wolf-like predator claims the lives of two women, leaving the community in fear.

Special FBI agents Nicole Beretti and Noah Jacobi, fan favorites known for taking on the toughest cryptids, are called in to investigate. What they uncover is far more chilling than they imagined: secrets buried in Ethan's family may hold the key to the predator's deadly attacks, and the danger might not just be outside.

Trapped by a relentless snowstorm, Beretti and Jacobi must protect Ethan, unravel long-held mysteries, and confront a ruthless creature stalking the townsfolk before it’s too late.

With gripping suspense, supernatural intrigue, and unforgettable characters, The Beasts of Blood and Spirit is a pulse-pounding thriller that will keep you hooked until the chilling end.
