From the back cover:
Christine Grandy-rebellious, wealthy, twenty-something - has disappeared into the depths of India, along with her hippie lover Monica Ward. Desperate to bring her home, Christine's millionaire father hires expert finder-of-missing-persons Paige Taylor.
But Paige discovers that the trail to Christine is mined with obstacles, as powerful enemies plot to eliminate her. Eventually, high in the Himalayas, Paige learns her traveling companions are not who they seem, this mission far more dangerous than she dreamed.
A witty, sophisticated mystery.
