Eeny, meeny, miny, moe. Catch a tiger by its toe. It's seared into Atlee Pine's memory: the kidnapper's chilling rhyme as he chose between six-year-old Atlee and her sister, Mercy. She never saw Mercy again. Three decades later, Atlee is an FBI agent assigned to the Shattered Rock agency, near the Grand Canyon. A mule is found dead and its rider is missing, but in this series debut, Atlee is abruptly called off the case. Risking her career, Atlee persists, sensing that the truth could spell the end of democracy in America as we know it.
