In You Can't Fool a Mermaid, college student and pianist Violet Bacon must save her highly anticipated concert from sabotage. With time running out, Violet rips into a flaw in the musical score and is blindsided by what she finds trapped behind the notes.
As theater seats fill and the house lights dim, Violet enlists three unlikely allies-a quirky busker, a Russian Blue cat, and an anchovy-sized mermaid-to help her set the score right. Together they must perform a little magic on a most bewitching evening or her performance will be doomed.
