When a sudden trail of death and desolation sweeps through south and central Texas, elements of the case trigger an alert with a division of the FBI that tracks possible supernatural influence. Agent Chimalis Burton, a specialist in cryptids of the Americas, has a history of vanquishing such monstrous creatures. When she is assigned the case, she scrambles to find answers before the situation worsens. Evidence begins to suggest an evil that has festered for centuries; an evil that now rises to reclaim its power. An evil that rests in the soulful eyes of a wolf.
