Cecily Campbell, a young knight sworn to protect the Independent Trade City of Housman, has her family's ancestral sword shattered in a losing fight against a crazed war veteran rampaging through the market. She's saved by Luke Ainsworth, a wandering blacksmith with a rare, forbidden gift for forging demon-infused blades. Cecily talks Luke into forging her a new sword, pulling him into her duties as a knight in a world still recovering from a war fought with devil-granted power.
