The Dark Lord’s First Christmas by Kathryn Le Veque

Jax de Velt is the knight they call The Dark Lord. After years of barbaric conquest across England, Scotland, Wales, and France, he finds himself six months into a marriage with a woman he has learned to love. The marriage is a happy one, but every day is a struggle as Jax learns to navigate a world where generosity and forgiveness are the norm. But one thing he hasn’t learned – the concept of human kindness and the warmth of the Christmas spirit.
In a brief happenstance with a peasant family, Jax comes to understand what, exactly, true bravery and kindness is.
The Dark Lord finds his Christmas heart.
