Selkie warrior Aalgur Thalon was born to fight in honor of the Dread One. She's going to win the Dusk Trials, join the elite Duskingr Air Fleet, and kiss her old life as a deckhand goodbye. But when her body betrays her, Thalon is forced to give up the biggest part of her identity. And that might just be the least of her worries. Thalon must learn the strength of vulnerability as she faces battles she's never trained for: Spindel Co. getting into everything and everywhere, villains in unexpected places, and worst of all, herself.
