The Devil's Heart — William W. Johnstone

It was in the summer of 1958 that the horror surfaced in the town of Whitfield, erupting like a festering boil, spewing its corruption on everyone near it. Those who survived the terror remember it as the summer of The Digging -- the time when the hot wind began to blow, when Satan's creatures rose from the putrid bowels of the earth, when the inhabitants of Whitfield were touch by THE DEVIL'S KISS

Now it was summer again in Whitfield, The town was peaceful, quiet, and unprepared for the atrocities to come. Eternal life, everlasting youth, an orgy that would span time -- that was what the Lord of Darkness was promising the coven members in return for their pledge of love. The few who had fought against his hideous powers before, believed it could never happen again. Then the hot wind began to blow -- as black and as evil as THE DEVIL'S HEART
