Among The Shoals Forever — Gail Z. Martin

Sorren and his privateers, Dante and Coltt, attempt to solve the mystery of a vanished heiress and a dangerous necromancer before there's hell to pay in 1780s Charleston.

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.
