It's dangerous to be a pirate. The seas have become more threatening than ever, with enemies closing in on all sides. War isn't just brewing--it's here, knocking on their doorsteps, threatening to devour them all. And just as she was warned, Emme might have been the one to create the chaos.

In her desperate attempt to keep the fight away, Emme hatches a plan that involves trapping the only one who can put an end to the battles. But as plans go awry, she discovers she's not the only one scheming. Eventually she'll have to accept that she's no longer playing a role: She's a pirate now. A pirate who will do what it takes to save her crew, even if it means oathbinding herself one final time.
