A gifted oracle, Lyssara, is betrayed by her husband Cassian for power and by her best friend Selene, then stripped of her crown and executed on the orders of Cassian's tyrant father, Lykos. The god Apollo grants her a second life — sending her back to the day of her engagement, now armed with knowledge of what's to come.
With the truth as her weapon, she shatters the doomed marriage, exposes Cassian's affair, and finds an ally — and forbidden love — in Kael, a fallen demigod and outcast half-brother. Together they uncover an ancient conspiracy: Lykos once murdered Lyssara's own mother, also an oracle, to seize divine power — and is now preparing the same fate for her.
