As they approach adulthood, Cat Barahal and her cousin Bee think they understand the society they live in and their place within it. At a select academy they study new airship technologies and the dawning Industrial Revolution, but magical forces still rule. And the cousins are about to discover the full ruthlessness of this rule. Drawn into a labyrinth of politics involving blood and old feuds, Cat is betrayed by her family and forced to marry a powerful Cold Mage. As she is carried away to live a new life, fresh dangers threaten her every move and secrets form a language she cannot read. At least, not yet. But both cousins carry their own hidden gifts and these will shape great changes to come. For in the depths of this treacherous world, the Wild Hunt stirs in darkness and dragons are waking from their sleep.
