Surrounded by cut-throats and slavers, Alessa knows there is more to existence than mere survival on the aerocks – landmasses that traverse the sky, powered by a volatile mineral. When the opportunity for a new life presents itself, there is nothing that will stop Alessa from having her way. Devan seeks the respect of his peers, rangers who protect their homeland Centara – an aerock so large that it can haul along smaller lands. When Alessa’s aerock makes landfall, they bring more than commodities and supplies for trade. They bring memories of past mistakes. They bring war.
