We love Elsa Beskow books, they are full of. whimsy and magic and sweet illustrations.
The children of the forest live deep in the roots of an old pine tree. They collect wild mushrooms and blueberries and shelter under toadstools when it rains. They play with the squirrels and frogs, and when fall comes, they collect and prepare food to see them through the long winter, until the warm spring breeze starts to blow.
