USA Today bestselling author Thea Harrison begins an all-new, darkly romantic paranormal saga, in which the fate of existence itself lies in the balance—and the key to victory may rest in the hands of two eternal lovers… In the hospital ER where she works, Mary is used to chaos. But lately, every aspect of her life seems adrift. She’s feeling disconnected from herself. Voices appear in her head. And the vivid, disturbing dreams she’s had all her life are becoming more intense. Then she meets Michael. He’s handsome, enigmatic and knows more than he can say. In his company, she slowly remembers the truth about herself… Thousands of years ago, there were eight of them. The one called the Deceiver came to destroy the world, and the other seven followed to stop him. Reincarnated over and over, they carry on—and Mary finds herself drawn into the battle once again. And the more she learns, the more she realizes that Michael will go to any lengths to destroy the Deceiver. Then she remembers who killed her during her last life, nine hundred years ago…Michael.

Having finally reunited, and fought off The Deceiver for now, Mary and Michael race up the Michigan peninsula to meet Astra before police forces catch up with them. But the closer they get, the less Mary is willing to trust a woman who by her own admission will do anything to finish The Deceiver – even if it means killing Michael and Mary to try again in another life. As they face their final battle unsure if they can trust either side, Michael’s loyalties are tested, making him vulnerable just when Mary needs him most.
