Anna and Sheriff Paul Davidson are married only three days before Anna moves from Mississippi to Colorado. Her mettle is immediately tested as the new district ranger at Rocky Mountain National Park. Three young girls have gone missing, and when only two return a month later--wearing filthy undergarments and bearing deep psychological scars--the signs point to a mysterious religious organization that guards its secrets closely. As a palpable sense of evil casts its shadow over the park, Anna puts her life on the line to discover the truth behind the disappearances.
