Calliope and the Royal Engineers. Calliope, #2

When Calliope board 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 shattered her dream of drawing plans for the ship in a quiet studio. Instead, she is thrust into politics at the highest level with enemies snapping at her heals as well as those who she isn't sure if they 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.
