Operaatio ilmastoareena (2022)

Nea, Niilo and Venla arrive for a summer holiday at Nea and Niilo’s grandmother’s house. The trip turns out to be more exciting than expected when they end up on an adventure with their new friends. A drone in the middle of the swamp uncovers a big hoax, and the friends do everything they can to expose it and perhaps save the entire planet. As well as a whirlwind environmental adventure, the book includes information on climate change.
