Betsy Bow-Linnet is determined to become a world famous concert pianist like her parents. There's just one problem: no matter how hard she practises she doesn't share their musical talents. So when a mysterious letter arrives from a woman claiming to know of an unusual Method that will make Betsy's playing 'stupendous', Betsy jumps at the chance. There's just one condition: she must keep the Method a secret.
But it isn't just one secret - it's forty-four tiny secrets in the shape of a boxful of pygmy mice! Betsy is mystified - how are they going to help her play the piano and - more importantly - how on earth can she keep them all a secret?
Gorgeously illustrated in two-colour, this is a warm, funny and pitch-perfect story about the true nature of family love and finding your real talents in the most unexpected of places.
