The most unexpected of all allies to Poseidon's warriors has proven to be the fiercest--Daniel, a vampire and Night Guild mage. But even the strongest alliance can be destroyed when an 11,000 year-old desire is reborn...

A vampire's oath, a maiden's quest...

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.

And the blackest of magic that could consume them both�

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.
