The knights of the Baltic Sea

Karin Henriksson 2012: Itämeren ritarit
illustrated by Harri Tarkka

Aino Ahven (perch), Harri Hauki (pike) and Kaisa Kampela (flounder) are eager pupils. Today they learn about scary things called humans.

The teacher tells them that humans are polluting their homes and force everyone to move. Aino, Harri and Kaisa want to talk some sense to the humans. Teacher  advises them to see Granpa Seal, who knows magis since he once was in the circus.
Aino, Harri and Kaisa meet Granpa Seal and get the ability to talk to humans. They swim to shore and meet some kids. The kids promise to do everything in their power to stop the polluting.

Very educational book about the poor condition of the Baltic Sea. When Kaisa and Harri are too deep in the dead part of the sea, it actually feels lifeless. The illustrations are that good. The importance of human action is greatly emphasised.
