I wrote this book to take children on a journey – aboard the school ship Bremerhaven and far beyond.
It tells the story of Lennart, a boy who has hated the sea ever since his father vanished without a trace in its depths.
But one night, when he discovers a mysteriously glowing message in a bottle, an incredible adventure begins.

But one night, when he discovers a mysteriously glowing message in a bottle, an incredible adventure begins.
Lennart meets the Klabautermann – the spirit of the sea – who takes him on a voyage across the roaring ocean. The waters are under threat from a dark force, and the Klabautermann needs Lennart’s help to stop it.
Together, they face the danger and uncover that the darkness is nothing but oil, spilling into the sea from an abandoned drilling platform.

On their journey, they not only discover the magic of the oceans but also learn that it takes courage to face your fears – and that even the strangest creatures can have a heart.
This book blends fantasy with reality, humor with environmental awareness, and tells children a story that shows how important it is to protect our oceans.
And perhaps... how to learn to trust again.
