Join Mouse on a new adventure as he leaves the urban bustle of a busy railway station and makes his way to a remote and majestic mountain peak. This journey has a distinctively autumnal feel to set it apart from Mouse's other adventures. The book also features a subtle message in the illustrations about biodiversity, showing the effects of over-grazing and even featuring mountain hares planting saplings to restore mountain forests.
