In the eternally frozen city of Hodeldorf, the Tattercoats live up on the roofs and by a strict code: only steal what you need, don’t leave a trace of yourself behind and if another Tattercoat is in trouble, you must always help them out. So when Otto’s mother goes missing and he is lured into a factory for children with nowhere else to go, the Tattercoats must come to the rescue. Dare they enter the Forest of Lost Things, where wolves, witches and other wonders hide in the shadows? And can they find a way to bring sunshine and warmth to Hodeldorf once more? An enchanting, curl-up-by-the-fire story of friendship and hope.
