There is something hidden in a hollow tree at Skull Island. This is what Peder’s grandmother
keeps repeating. Kristina, Peder and their friends are back at Wendelby horse riding camp and they need to somehow get to the hostile-looking island to find out what the secret is — the family secret that Peder’s great-grandfather took to his grave.
Peder finds a diary that belonged to his great-grandfather, who fought for Norway in the Second World War. His notes take them back to the freezing winter of 1943, when he was part of an undercover sabotage group in the mountains. Why has Peder’s family never talked about this?
As the past is revealed, so is the secret, but the last piece of the puzzle is still missing.
