Pollyanna, by Eleanor H. Porter

Orphaned by her father and mother, Pollyanna, an 11-year-old girl, is taken in by her aunt Polly, her only living relative. Rich and uncompromising, the aunt lacks understanding and affection, and welcomes the girl into her home as a duty. Pollyanna, in turn, is a charming girl, who conquers everyone with her passion for life and for people, her optimism, her joy of living... and 'the glad game', which she practices and teaches to anyone who wants to learn. A game where no one loses, everyone wins - and transforms. A classic of universal youth literature, published in 1913, this book has been enchanting generations of readers of different ages in different languages, having become mandatory and necessary reading for anyone who wants to see life without bitterness, always discovering the bright side of everything.
