Willow North is a thief, and despite her secret magical talent for sensing worked metal, she has never wanted to be anything else. But when her former fiancé appears on her doorstep with the eight-year-old King of Tremontane in tow, she is drawn into the political conflict surrounding the boy King's ascension. His uncle, a powerful Ascendant with the magic of manipulating the elements, murdered the old King and intends to kill young King Felix.
Willow intends only to take the boy to safety, but as the days pass, she finds herself increasingly attached to Felix and unwilling to leave him once he's safe. But the pretender to the Crown has a long reach, and as his men close in on the fugitives, it seems nowhere may be safe.
