Perfect for reading together or for children who are just starting to read alone. Filled with gorgeous illustrations. Willow Valley is a very special place. Nestled in a hidden valley, trees of all shapes and sizes grew on the rolling green hills and pretty flowers dance in the meadows. Only the animals who live there know their way in and out, but they hardly ever want to leave because they’re having too much fun! Riley the mouse, Starla the badger and Horatio the hedgehog are the best of friends. When Riley’s sister Mimi Rose goes missing, the friends know they have to find her before it gets dark. Where can she be?
