Book excerpt: Brazilian-born doctor André Cabral is living in London when one day he receives a letter from his home country, which he left nearly thirty years ago. A letter he keeps in his pocket for weeks, but tells no one about. The letter prompts André to remember the days of his youth - torrid afternoons on Ipanema beach with his listless teenage friends, parties in elegant Rio apartments, his after-school job at his father's plastic surgery practice - and, above all, his secret infatuation with the daughter of his family's maid, the intoxicating Luana. Unable to resist the pull of the letter, André embarks on a journey back to Brazil to rediscover his past.
