One More Knight by Cynthia Luhrs

Some balls end with a glass slipper while others end with a blade at your throat.

When Lily tumbles through time to medieval England, she happily gives up all thoughts of pizza, hot showers, and modern technology and vows to soak up every bit of the past so she can tell her best friend when she returns home… In a few days at the very most.

Tristan de Savage is haunted by loss. He’s facing threats to his castle, his page thinks he saw a fairy in the gardens, and winter is coming. When a woman appears at Weddington Castle, Tristan swears the fates are laughing at him, for he has no time to aid a damsel in distress, no matter how enchanting.
