Serai has spent the past eleven thousand years locked away in a crystal cage below the sea on the lost continent of Atlantis. Serai, once a princess, was asked by her father to submit to the long slumber while she prepared to marry Atlantis' future king. But when her intended decides to marry a mortal instead, Serai is left in a deep sleep for eleven thousand years. Daniel was Serai's greatest love before Atlantis sank into the sea. When an army of invaders ravaged Atlantis, Daniel shielded Serai from a possible death only to almost lose his own life. When Daniel was on the brink of death, he was bitten by a powerful vampire. But when he awoke to his new existence, he found that Atlantis was no more. It had disappeared into the sea taking the woman he loved with it.

Daniel attempted to accept his fate and tried to live his life without Serai. Thousands of years later, mortals accepted the existence of vampires and witches. Daniel, in fact, held public office. He was ruler of all North American vampires. But eleven thousand years of blood, murder, and painful memories leave Daniel without a will to live. After he resigns his post as Primator, Daniel attempts to take his own life by allowing sunlight to consume him. Only death does not visit him as the sun rises, instead, Daniel is face to face with the woman he thought he had lost forever thousands of years ago.

When a very powerful gemstone, which held the ultimate power over Serai and the other sleeping maidens, malfunctioned Serai managed her escape. The stone named the Emperor is in fact a gem taken from the trident of the god, Poseidon. It holds enormous power not only over the women who have been sleeping for thousands of years, but it is also the key to Atlantis' return from his watery grave. The Emperor, however, has fallen into the hands of a dangerous sorceress named Ivy. Completely unaware of the gem's great power, Ivy futilely attempts to use it, only to be caused unbearable physical pain by the gem's power. Serai and her sleeping sisters also grow weaker every time Ivy attempts to handle the stone.

Ivy, however, is not working alone. She is being helped by a vampire named Nicholas and his mortal partner who have sinister plans for all mortals on earth. With Ivy's help, they plan to take over all financial institutions and convince mortals that Atlanteans are evil, which will destroy Atlantis' final hope of regaining its rightful place in the world.

Part of Alyssa Day's The Warriors of Poseidon series, VAMPIRE IN ATLANTIS, is a fairy tale vampire romance with a historical twist. The novel reads a bit slow in the beginning, and the bad guys weren't developed enough and play a very small part of the novel. But Daniel and Serai's sleeping beauty romance seals the deal. Magically romantic, with just the right amount of Atlantean humor, Alyssa Day has resurrected Atlantis!
