Sofia is a bold and hot-tempered child, unlike her grandmother, who takes care of her after her mother's death. Every summer, you go on a new adventure together of a different kind: exploring parts of the island you live on, meeting new types of birds, swimming in the dangerous bay without Sofia’s father knowing, sleeping in a tent, building a miniature model of Venice, and writing a book about insects. . Without addressing their true feelings, they spend their days in endless conversations and discussions about everything: the meaning of life and death, the nature of God and Satan, heaven and hell, and the concepts of love, family, friendship, and tolerance. By creating an integrated world on a small, isolated island, Tova Jansson writes - in a magical style, and simple sentences loaded with profound concepts - a sweet novel about the friendship between a child who begins her journey in life, and her grandmother, who is approaching the end of this journey.
