3rd World Products, Book 11

Mysterious, untraceable uses of Amaran energy fields in the vicinity of The Grand Canyon are noticed by automated monitors. Thinking someone has somehow stolen or constructed field manipulation devices, 3rd World Products sends Ed to discover the source of the field emanations. Instead of illicit devices, he encounters a young woman who can manipulate field energies using only her mind. She's the first natural field user in history, but she's also hiding from Arizona drug dealers and a possible murder charge.
