Spending her vacation away from the city and her friends was not what Pii had in mind for the summer she had been eagerly waiting for. And then even the holiday house turns out to be strange and peculiar. Who is the boy who moves around the house as if it were his own, and why can't anyone else see him?

Pii's experience of being an outsider turns into a strength, because she sees things that others don't notice. Soon she finds herself in the middle of a secret that overshadows the sunny idyll of the small village. Are the thefts of vacation homes and the unsolved death that happened half a year ago related? And what does the mysterious boy in the green cap have to do with all this?

Pii has to look for answers deep below the surface, and while diving for them, she also has to face herself. A vacation Pii expected to be boring turns into a journey of self-discovery, and in the end nothing - not even the ghosts - is what it seemed at first.

A wonderful and surprising description of the need to be seen and the pain points of family and sibling relationships.
