At last, pirate Aster Oberon is setting sail—but danger is on the horizon. Armed with her crew of family and friends, Aster is pursuing the evil queen Morana in order to save the world as she knows it. Her heart is desperately torn between Will and Titus, but she’ll have to put her feelings aside to destroy the Underling army once and for all.

Unfortunately, Aster isn’t the only one hunting. Morana is seeking three mythical treasures: a helm that reveals the entrance to Elysia, a key to unlock the gates, and a sword to vanquish the creature within. If Morana is successful in her search, she could destroy the barrier between the heavens and their realm. Now, Aster must race to find the relics first, if she has any hope of bringing peace to the Known World.

But some things would rather stay hidden. When the discovery of the treasures comes at a devastating price, Aster must push past her deepest fears and step into her true power, or else risk dooming the world to darkness.

Fearsome sea creatures, heartbreaking betrayals, and desperate desire fill this exhilarating new installment of the Nightweaver series and the finale to Aster’s journey.
