Bad Memories — Gail Z. Martin

Set in modern-day Charleston. When construction workers expose a mysterious artifact in the walls of a centuries-old building, Cassidy, Teag, and Sorren must battle vengeful ghosts and hungry ghouls to keep the death toll from rising.

This series of adventures spans over 500 years, from the 1500s to modern day as a small cabal of vampires and their human helpers battle supernatural enemies to find and destroy dangerous magical items and keep the world safe from dark forces.
