Katherine "Kat" Jones is not your typical damsel in distress. She's an outspoken New York City fashion editor, whose job is to claw through the hype and sniff out the trends. But an assignment at a medieval fair suddenly gets out of hand when Kat finds herself not at a modern fair but back in the actual time of King Arthur's court. Suddenly Kat needs every ounce of her 21st century wits to navigate the legend. After all, surviving a magical plot, an evil prince, and a case of mistaken identity—all without changing history or scuffing your Manolos—takes some doing!

Luckily, she's got her very own knight in shining armor, Lancelot du Lac, on her side. The honorable-to-a-fault and devastatingly handsome champion insists on helping her out, even though she's not quite sure she wants him to. After all, shouldn't he be off romancing Queen Guenevere or something? Will Kat manage to stay out of trouble long enough to get back to her beloved cappuccinos, cosmopolitans and cashmere? And what will Lancelot's forbidden love mean for the kingdom of Camelot?
