As a physician in the ER of a rural South Carolina hospital, Dr. Rhea Lynch is a dedicated healer, a woman of science, and to some degree, a skeptic. But her most fundamental beliefs are put to the test with the arrival of a traveling faith healer, whose "cures" produce some baffling mysteries: a young quadriplegic woman can suddenly move her arms; a chronic pain sufferer begins to dance again. Events go from bizarre to deadly with the arrival of a gravely injured but violent young woman determined to practice a dark, deadly magic. As the pieces of this puzzle begin to fall into place, Rhea will find her beliefs, her skill and her understanding tested in unfathomable ways as she enters a realm where science and strange faiths collide.
