You swore to stand between him and death. Nobody warned you about his mouth.
The king is dead, the prince is framed, and the usurper's knights are closing in. At midnight in a ruined
chapel you — a blacksmith's son with a borrowed shield — swear the ancient oath to protect Prince Casimir with your
life.
He is brilliant, grieving, and the rudest man you have ever met. Get him across a hunted kingdom, win back his crown,
and find out what happens when a sworn shield falls for the one person he's never allowed to reach for.
