A profound detective story meets a moving exploration of gender, identity, and the search for happiness in Sergio Y, the recently translated, award-winning novel by Brazilian lawyer, human rights activist, and author Alexandre Vidal Porto. Narrated by renowned São Paulo therapist Armando, the story unfolds as Armando attempts to unravel his role in the life and death of a young male patient—who abruptly left Armando's care, and whom Armando later discovers had been living in New York as woman until her recent unexpected death.
