"YOUR FATE IS NOT YET SEALED.
EVEN IN THE DARKEST NIGHT, A STAR WILL SHINE,
A BELL WILL CHIME, A PATH WILL BE REVEALED."
This book is classified "juvenile," but I think it's the kind of book that can appeal to readers of all ages. A boy named Otto gets lost in a dark forest in Germany, and is assisted by three sisters who are somehow also characters in a mysterious fairy tale he bought from a gypsy, who also gave him a very special harmonica. The sisters need Otto's help to break a witch's curse, and the harmonica will be the key. A kind of "Fellowship of the Traveling Harmonica" ensues. The harmonica will be passed along multiple times, and the narrative follows to each person who possesses it. Just a bit of a warning: The switch from one narrative to another is jarring when you don't know it is coming, especially since the narrator gets you to care about the characters, takes you to a cliffhanger, and then switches to a new set of characters. Don't worry--the story comes back to those characters, resolves the cliffhangers, and ties it all together. Just expect it and go along for the ride.
This is an instance where listening to the audio edition is the best choice, because music is so central to the story, and every musical piece mentioned is also played in the audio version. I can't help thinking something is lost in the text-only version.
