Vampire in Atlantis (Warriors of Poseidon, 7)

A vampire's oath, a maiden's quest... And the blackest of magic that could consume them both... Daniel, vampire and ally of the Warriors of Poseidon, has fought on the side of humanity-even against his fellow creatures of the night-for more than 11,000 years. But the crushing weight of futility and the reality of always being starkly, utterly alone has forced him to finally give into despair. He took the first step into the sunlight that would destroy him-and instead walked into Atlantis. Eleven thousand years ago, Serai was one of a group who agreed to be placed into magical stasis to ensure the future of the Atlantean race. When a dark sorceress steals the gemstone that protects her sleeping sisters, she awakens to a vastly changed world-and the one man she could never, ever forget. And with an ancient evil tracking their every step, the long-lost lovers must battle both the darkest of magic and the treacheries of their own hearts.
