The story tells of Sha, a lost city in the "desert of time", known as the city of forgotten things. It is ruled by an old blackbird who takes care of forgotten things and puts everything that arrives in order: keys, toys, old photos but also words, ghosts and fears. In Sha «words are recalled; pampered and nourished, fears and ghosts as well as dreams », reads the synopsis of the book. “Wars also pass through Sha, because even those are forgotten. But every night Sha is renewed: the desert turns into a sea and all the houses change places until the moon plunges into the horizon."
