Touched by a very public tragedy, musician Rob Quillen comes to Cloud County, Tennessee, in search of a song that might ease his aching heart. All he knows of the mysterious and reclusive Tufa is what he has read on the Internet: they are an enigmatic clan of swarthy, black-haired mountain people whose historical roots are lost in myth and controversy. Some say that when the first white settlers came to the Appalachians centuries ago, they found the Tufa already there. Others hint that Tufa blood brings special gifts. Rob finds both music and mystery in the mountains: close-lipped locals guard their secrets, even as Rob gets caught up in a subtle power struggle he can't begin to comprehend. A vacationing wife goes missing, raising suspicions of foul play. And a strange feral girl runs wild in the woods, howling in the night like a lost spirit.
