Sylvi Quine, the best rig driver on Layce, has braved the dangers of the Shiv Road to save her friend and learned the truth of her power over Winter. Now, she's joined the rebels working to take down the Majority. Her magic could change the course of their fight, and she agrees to meet the king of Paradyia to offer an exchange: the healing powers of the Pool of Begynd for his army.
The journey won't be easy. To get there, Sylvi will have to navigate the Kol Sea, crossing through Winter's storms and swarms of her Abaki––all while outrunning the Majority, who have sent their best Kol Master to track her down and bring her in, dead or alive.
But she isn't traveling alone. Mars Dresden knows Sylvi is the key to freeing Layce, and demands she train like it. Kyn, the boy with stone flesh and a soft heart, is bound to Sylvi in more ways than one, a connection that both hurts and heals. And Lenore, Sylvi's best friend, insists the Majority pay for what they’ve done to her parents. Even though her crew believes in her, Sylvi's still learning to use her power, and Winter’s whispers are constant . . .
Will she be able to control Winter when it matters most? Or will this be the end of the rebellion?
