The first thrilling book in the most exciting children's fantasy series since Harry Potter. They were taken from their beds one frozen night, when the world was covered in snow. Ten years on, Kate, Michael and Emma have grown up in a string of miserable orphanages. Arriving at Cambridge Falls, the children quickly realise there is something different about this place. As they explore, they discover an old, empty leather book. The moment they touch it, an ancient magical prophecy is set in motion, and the children are thrown into a dangerous alternate reality of dark enchantments and terrifying monsters.
