'Twas the Executioner Knight Before Christmas (The Executioner Knights #6.5)
Kathryn Le Veque

No one survives an Executioner Knight and least of all, Maxton of Loxbeare. But when he married his wife and had children—three little girls, right away—Maxton grew a heart. He became a devoted and dedicated father who loved his children dearly. But the Executioner Knight in him still lived. So after a very bad dream, Maxton sees that, for his daughters’ sake, he must change.
