Outer Dark by Cormac McCarthy

Draw a line from William Faulkner through the midnight dark of the human soul and at the end of it you will find Cormac McCarthy, picking over the bones of murderer and murdered, like some oracle seeking the truth of the ways of man and god. McCarthy's god is, at best, indifferent. At worst, malevolent and sadistic.

Set in the mythical southern Appalachia of Faulkner, this novel is sparse and stark. It follows an incestuous brother and sister. She bears his child; he abandons it to the elements. The baby is taken by a passing tinker. She sets out to find the baby. The brother sets out to find her. Along the way they encounter good and evil in many forms. Look for no happy ending here.
