At the Academy of Angels and Demons, peace is nothing more than a carefully controlled illusion. Years after the war that nearly destroyed Heaven and Hell, immortals are forced to coexist under strict balance laws inside the academy from Heaven’s Secret. Angels and demons walk the same halls, attend the same classes, and pretend the tension between them isn’t one bad decision away from exploding again. But the academy’s biggest threat isn’t hidden anymore. Malbonte lives among them. The forbidden half-breed Heaven once tried to erase now exists inside the academy under an unstable political agreement that nobody truly trusts. Some immortals fear him. Others worship him. Most avoid looking at him for too long. His existence alone keeps the entire academy on edge. When Y/N arrives, she quickly realizes this place is far darker than the stories make it sound. Rumors spread constantly. Students disappear quietly. Power matters more than morality. And beneath the beauty of the immortal world is something rotten enough to tear Heaven and Hell apart all over again. Worse, something about Y/N feels… wrong. Ancient magic reacts strangely to her presence. Certain records about her are missing from Heaven’s archives. And for reasons nobody understands, Malbonte starts paying attention to her. In a world built on segregation, fear, and divine hypocrisy, attraction becomes dangerous, loyalty becomes political, and balance itself begins to crack.
