Seventeen-year-old Arden and her boyfriend, Subra, are inseparable. Both orphaned as kids, their friendship blossomed into young love. But while she dreams of their future together, he dreams of treasures beyond their shores. When pirates attack their home island and abduct Subra, Arden is left without friends or family, and no way to follow. In her desperation, she makes a dubious deal with an eccentric captain named Bato and his quirky crew to save Subra.

To Arden's amazement, Bato's ship doesn't just sail on the seas. It can fly among the clouds. Catapulted into a swashbuckling adventure across the wild sky, Arden's resolve is tested with thrilling airborne heists, breathtaking battles against aerial fleets, and grand galas hosted by sinister Pirate Lords. As fate pulls Arden and Subra in different directions, they will have to find a way to reconcile love and destiny or risk losing each other forever.
