Every year, on the night of the first full moon of summer, the sea anemone holds its first dance exclusively for the moon. This year, however, a mysterious shadow slips into the half-submerged town and snatches as many little flowers as it can from the heart of the anemone.

Who is the intruder and for what purpose did they steal the flowers? Peter and Lydia follow his trail and confront the dark side of human intelligence.

A book that speaks to the young reader about egoism and arrogance, fairness and injustice, as well as the happiness one can find in the simplest of things.
