An impossible diplomatic mission. Dangerously growing magic. A distrustful crew. Can Nile beat back the rising tide of war before it’s too late? Six months have passed since Princess Nile Greysik changed the course of the Tirik war and earned her place in the Felielle navy . . . or thought she did. With the war taking a violent new turn, Nile—joined by a cryptic empath named Kyra—sails out to beg support from the isolationist Diante Empire. But with a chauvinistic crew waiting for Nile to fail and even Domenic questioning her authority, one wrong step could strip Nile of her command mid-voyage. When a terrifying new evil strikes their ship, Nile begins to understand the awful truth about the enemy they’re facing—and this time, not even her wind calling may be enough to save them.
