Brynn has spent her entire life among the Alaha, a seafaring people exiled generations ago after a devastating war. Though she isn't one of them by birth, she has trained to become one of their elite guards and dreams of proving her loyalty.

Everything changes when she attends the annual market held by their enemies, the Kenta.

There she encounters Acker, a powerful Kenta soldier capable of wielding enchanted metal. He reveals that Brynn's past—and even her identity—has been hidden from her. What begins as a chance meeting soon unravels into political conspiracies, forbidden magic, dangerous sea voyages, and a romance that forces Brynn to question everything she believes about home, loyalty, and love.
