Maia has spent her entire life in a tower on the island of Altheia. Placed there for her protection, she is haunted by fear as well as the murmurings of the skeletal pirate-spirit Arlo. One quiet morning, her peaceful existence is disrupted by the arrival of all she’s ever an engagement to her guardian’s son Evander and a chance at a family of her own. But on her wedding day, her beloved tutor goes missing, and her world begins to unravel. Maia will have to navigate prophets, sea-wolves and liars as she learns the truth of her identity, and community beckons her beyond the dark whisperings that keep her chained to her island.
