The tale of young Hannah, who loves above all else to sing. What worse curse could have been visited upon her than this: she has been sent to live with her aunt and uncle in a sorrowful town where music itself is banned from its grim and cobbled streets. What woe has befallen this town? Why are there no children? Why are there no rats? Hannah will discover the answers to these dread questions in the wilderness wastes, under a mountain. There she discovers a secret orchestra, held captive by an ancient conductor, who remembers his glorious youth – when no-one could resist the beauty he could make with his flute. Could our Hannah be the bridge between two ancient enemies? Might the ghosts of the rats come to her aid? And, most importantly, will she sing once again?
