Paulo Coelho, one of the world's best loved storytellers, is back with a riveting new novel set in London. This is the story of Athena, or Sherine, to give her the name she was baptised with. Her life is pieced together through a series of recorded interviews with those people who knew her well or hardly at all – parents, colleagues, teachers, friends, acquaintances, her ex-husband. The novel unravels Athena's mysterious beginnings, via an orphanage in Romania, to a childhood in Beirut. When war breaks out, her adoptive family move with her to London, where a dramatic turn of events occurs… Athena, who has been dubbed 'the Witch of Portobello' for her seeming powers of prophecy, disappears dramatically, leaving those who knew her to solve the mystery of her life and abrupt departure.
