“Elara Vex had everything-a flawless ice core, the title of prodigy, and a place at the pinnacle of the High Tower. But in one brutal night, it was all ripped away. Her mentor tore the core from her chest. Her fiancé drove a sword through her back. Her own sister smiled as she bled out on the cold marble floor. When Elara wakes, she's years in the past, mere hours before her core is scheduled to be stolen. This time, she won't be anyone's sacrificial lamb. She shatters her own core with forbidden blood magic and forges something far more terrifying in its place-a bottomless, ravenous Chaos Core that devours magic itself. Now, branded a worthless cripple and cast into the deadly Abyss, Elara is pulled from the darkness by the outcasts of Elysium Academy-a school for heretics, psychopaths, and everything the Tower despises. Under the tutelage of a reclusive principal who knew her murdered mother, Elara will master her forbidden power and uncover the Tower's darkest secrets. When the Five Academies Ranking Tournament arrives, Seraphina Vex stands in the arena, draped in white saintess robes, ready to claim ultimate glory. She doesn't know that a ghost from her past has clawed her way back from hell. She doesn't know that Elara is coming-and this time, the prodigal sister isn't asking for mercy. She's bringing chaos.”
