What does it mean to grow up knowing that the forest is alive — and that protecting it means protecting all of us? Helena grows up between two very different worlds: Sarayaku, a Kichwa community in the Ecuadorian Amazon rainforest, and Finland. From her family and her people, she learns that the forest is much more than a place: it is a living world of trees, rivers, animals, stories and traditions that must be protected. As Helena grows older, she discovers that her voice can travel far beyond her homeland. From climate conferences to international meetings, she speaks out for the Amazon and the rights of Indigenous peoples, showing that determination, dialogue and courage can help defend what matters most. Written for children aged 6 to 12, Helena – The Sentinel of the Amazon combines an illustrated true story with engaging educational activities, including a colouring activity, geography, quizzes, word games, syllables and a word search with a secret message. A book for young readers who are curious about nature, different cultures and the world around them, and a useful resource for parents, teachers, educators, schools and libraries looking for an accessible way to explore environmental protection, Indigenous cultures, climate awareness and civic responsibility.
