In the quiet Wyoming town of Mercy, Sheriff Hank Whitaker has kept the peace for twenty-three years—until the day he vanishes without a trace. His loyal deputy, Lila Monroe, uncovers boot prints, an open door, and a cryptic note demanding the long-sealed Blacktail Mine stay closed. As suspicion falls on a slick Denver developer hungry to reopen the dangerous site for rare-earth riches, Hank reappears battered but unbroken, revealing a kidnapping and bribery scheme with local betrayal at its core. With grit, humor, and small-town loyalty, Hank and his team expose the truth before the mountain claims another victim.
