Narrowly surviving assassination and capture, Octavia Leander, a powerful magical healer, is on the run with handsome Alonzo Garrett, the Clockwork Dagger who forfeited his career with the Queen’s secret society of spies and killers-and possibly his life-to save her. Now, they are on a dangerous quest to find safety and answers: Why is Octavia so powerful Why does she seem to be undergoing a transformation unlike any witnessed for hundreds of years

The truth may rest with the source of her mysterious healing power-the Lady’s Tree. But the tree lies somewhere in a rough, inhospitable territory known as the Waste. Eons ago, this land was made barren and uninhabitable by an evil spell, until a few hardy souls dared to return over the last century. For years, the Waste has waged a bloody battle against the royal court to win its independence-and they need Octavia’s powers to succeed.

Joined by unlikely allies, including a menagerie of gremlin companions, she must evade killers and Clockwork Daggers on a dangerous journey through a world on the brink of deadly civil war.
