The Wonderful Adventures of Nils is written about as a children's book, and in essence it is. Nils is a young mischief-making boy who likes to pick on animals until he is transformed into miniature by an imp. After learning a little humility, Nils goes on to ride with a crew of geese across Sweden, and has many adventures with crows, foxes, ducks, a cow, a dog and other animals, and even some mythical beings and places.

But deeper than this, Lagerlöf has written an environmental call to action that is 100 years ahead of its time. Nils learns to love his world and those in it by becoming part of it. His transformation is gradual but complete, made richer by the wonderful prose and incredible descriptions of Sweden from a goose-eye-view (Lagerlöf must have hired a hot air balloon for research, surely). Myth and story blend with compassion, humour and empathy in short chapters, so many that are wonderful even taken alone. An unforgettable book, for children of mind or body.
