Brash, cocky, and unbeatable with a sword (well, almost), Sam of Haywood is the most promising Paladin trainee in the kingdom of Thule… and knows it. The only problem is that Sam is really Lady Samantha, daughter of the seventeenth Duke of Haywood, and if her father has his way, she’ll be marrying a Paladin, not becoming one.

But Sam has never held much interest in playing damsel-in-distress, and so she rescues herself from a lifetime of boredom and matrimonial drudgery. Disguised as a boy, Sam leaves home behind to fight demons-—the most dangerous monsters in Thule—-alongside the kingdom’s elite warriors. Pity that Tristan Lyons, the Paladin assigned to train her, is none other than the hero of her childhood. He hasn’t recognized her–yet–but if he does, he’ll take away her sword and send her packing.

Sam is not the only trainee hiding secrets: Braeden is a half-demon with a dark past that might be unforgivable. Whether he can be trusted is anyone’s guess, including his.

As demons wreak havoc across the land, rebellion stirs in the West, led by a rival faction of warriors.
