After the IT firm where she works shuts down, Lucâia has a vision of her future career as a taxi driver, brought on by the intoxicating opera floating through her apartment's air vent. She obtains her taxi license and meets the neighbor responsible for the music. Calaf, he says, is his name, also the name of the character from Puccini's Turandot and the name of the bird Lucâia received on her 10th birthday from her long-since-dead mother. When Calaf moves out of her building, Lucâia becomes obsessed, driving through Madrid and searching for him on every corner, meeting intriguing characters along the way. What follows is a surreal tale of superstition and coincidence, featuring Millâas's singular dark humor. Let No One Sleep is a delirious novel in which the mundane and extraordinary collide, art revives and devastates, and identity is unhinged by the forces of globalized capitalism"--
