Nightfall — John Farris

No one can stop Dark Angel... His heritage is violence and terror. A creature of nightmare, shunning all that is good in mankind, he kills without warning, without mercy. Only once has his prey survived. Scarred emotionally and physically, Anita fled to the sanctuary of Lostman's Bayou. But the quiet of the swamps holds no peace - she cannot escape the terror. Angel will find her. Then she will die.
