Caerlon is a kingdom where the power of Resonance has long been bound to a single bloodline, a single all-powerful ruler. Now, for the first time in centuries, the magic has been divided.

On the night of the new king's coronation, something causes his magic to fracture, and Catanya, a young woman living on the outskirts of Caerlon discovers the long-kept secret of her connection to the throne.

Driven mad by his lust for power, King Cadyan sends his soldiers to hunt her down. He is determined to reclaim his birthright and uncover the truth about the legendary Relics of Illayan, which could hold the key to eternal power and immortality.

On the run, terrified and alone, Catanya must decide how-or even if-she can wield the magic of Caerlon to protect herself and save everyone she loves.
