When her true identity is finally revealed, those who humiliated and abandoned her beg for forgiveness. But the fall of the Northern Wall awakens an even darker threat: the ancient magic mirror, the Abyssal King, and a shocking secret about Yara’s past that could determine the fate of all humanity.
