War is coming, whoever rules the air will be unstoppable. When Cal boarded the Kestrel as First Mate after the Crown Prince asked her to build him an airship, she expected to learn command, as he'd insisted, but dangers at sea, then at home shatter her dream of drawing plans in a quiet studio. Instead she is thrust into politics at the highest level, enemies snap at her heels and some who she isn't sure if they are enemy or friend. Intrigue, betrayal, danger, none of that is going to stop Cal from giving her country the best airship in the world. All she needs to do is survive.
