Dawn of the Vampire
By William Hill, 1998

"Wreythville's cemetery had rested quietly under South Holston Lake, but now the receding waters exposed an island of graves. And as the tombstones emerged, so did the unstaked dead that had been buried beneath them. Freed, the ancient breed of vampires arose with a frightful new power, seeking vengeance."
