A little boy called Oliver moves into an old house with a modern extension, where he lives in a luxury flat. He could use a private lift if he wished, but he prefers to go up and down the dingy stairs, where he loves to read and where he meets his new neighbours. He is a year older in each successive story. In some, he just flashes past; in others he is the central character. Everybody knows him, although they often don’t know each other. The tenement’s inhabitants would prefer to be islands, but this isn’t possible. They have too much in common. Stairs, steps, and holes in the ceiling.
The main themes of the book are neighbors, relationships, intergenerationalism and otherness.
