On Blood Moon night, Pureblood Princess Seraphina is betrayed. Her husband Marcus and stepsister Esther disfigure her and cast her into the Sacred Blood Abyss. Seven days later, Marcus seizes House Ashbourne's scepter. But Isabella, Seraphina's twin, senses her sister was murdered and assumes her identity to infiltrate the court. She withstands Marcus's interrogations, Esther's terror, and Blood Hound trials. Marcus plots to expose her at the Council of Elders, but Isabella already holds the blade of truth. Under the Blood Moon, this game of impostor revenge and identity war has just begun.
