Genetic memory, specific information encoded in DNA, both haunts and teaches. As birds "remember" how to build nests, so people recall the ancient voices and visions of their ancestors. This is the story of a family, and how each one is guided by the unspoken passion that flows in them, as real as blood. Set in the mystic hills of northern New Mexico, The Passionate Line paints a landscape of quiet beauty, overlaid by rich portraits of its characters.
