The Bard's Daughter is a prequel novella to the Gareth & Gwen Medieval Mysteries:

As a bard's daughter, Gwen has spent her life traveling from castle to castle and village to village with her family, following the music. In the winter of 1141, Gwen's family is contracted to provide the entertainment for the coming-of-age celebration of a lord's son. But before the celebration can begin, Gwen's father is found over the body of his friend, with a harp string as the murder weapon and blood on his hands.

With the lord of the castle uninterested in finding the true killer, it is up to Gwen to clear her father's name before her father's music is silenced ... forever.
