Cry for the Strangers

Clark's Harbor was the perfect coastal haven, jealously guarded against outsiders. But now strangers have come to settle there. And a small boy is suddenly free of a frenzy that had gripped him since  birth... His sister is haunted by fearful visions... And one by one, in violent, mysterious ways the  strangers are dying. Never the townspeople. Only the strangers. Has a dark bargain been struck between the people of Clark's Harbor and some supernatural force? Or is it the sea itself calling out for a human sacrifice?
