John arrives in a Montreal airport with a suitcase in hand. We do not know where he is from, or who he is. He takes up work as a night-shift nurse and writes his reflections and impressions in a notebook that he carries with him at all times. By means of these personal entries, the novel allows us to explore his identity by following his daily movements and intimate thoughts, as well as his connections to those who come into contact with him. Based in a Montreal neighbourhood called Carr? St Louis, the story unfolds through non-linear narrative connections that flow across city blocks, continents and oceans, and meander in and out of the characters' minds, dealing with questions of displacement, identity, and meaning.
