Former Detective Tal Davis is no stranger to heartbreak and loss. She, Link, and Avani were all saved from their broken lives by becoming Vessels-human hosts for spirits who return to right wrongs from their past and earn a chance at Elysium. Each Vessel was inked with the portal tattoo, and each still carries the ancient coin that protects them from danger. But the coin is also a doorway to the other side, and one dark, vengeful spirit is determined to get through. In this supernatural, contemporary, science fiction sequel to "The Vessels," Tal and the others face their gravest dangers yet to protect their ancient, mystical program, survive their life-threatening spirit journeys, and save humankind from the growing evils that lurk in the beyond.
