Three years ago, her family was ripped away-taken by the very person who saved her life. Since then, Mabel's existence has been a quiet fight to survive-bullied in school, beaten by the only family she has left. When a boy who looks just like her past rescuer reappears and saves her, everything changes. He drags her into a world she never knew existed. Dragged to Hira Institute, a hidden academy carved into the mountains, Mabel is thrust into a world where vampires, shapeshifters, telepaths, and monsters walk in daylight, concealed from human eyes. Noah leads one of the most feared military supernatural forces: The Transcendents, elite soldiers born to protect the balance between the human and supernatural world-or destroy it. But in Hira, peace is an illusion, trust is a weapon, and the truth about Noah may shatter more than her heart. Mabel soon learns she's the last of a race thought extinct-a race whose existence could crown a ruler or burn the world to ash. Haunted by her sister trapped in a coma, Mabel clings to hope-finding others like her, uncovering her mysterious heritage, and most of all, bringing her sister back. But the peace is a lie. When betrayal cuts deepest-Noah's and Mabel's past is revealed-their fragile bond becomes a curse: destined to bring them together, yet doomed to tear them apart. As Mabel fights to master a deadly force that's turning her into something else, something dangerous, she's forced to face the cruel truth: To survive, she may have to let go of her humanity. And once she does... there's no turning back.
