Ask Not the Moon — Tori Minard

In ancient Atlantis, devotion and most contact between Amaki and human is forbidden. Yet Kistalleh Waverider, Atlantean noblewoman, and Garek of Nissa, embittered Amaki slave, find love and acceptance in each other's arms. They'll do whatever they must to be together, even when separated by death and thousands of years. In modern America, Garek must rescue Kistalleh--now known as vampire Callista Harris-- from the evil Dark Empire and help her recover her lost memories of him before death tears them apart again. The trouble is, in her modern incarnation Callista hates and fears everything Garek stands for.
