The Angel's Game (El juego del ángel, 2008) is a prequel to 2001's The Shadow of the Wind by Spanish author Carlos Ruiz Zafón. Like The Shadow of the Wind, it was translated into English by Lucia Graves, daughter of the poet Robert Graves, and published in 2009. The Angel's Game is set in Barcelona in the 1920s and 1930s and follows a young writer, David Martin, who is approached by a mysterious figure to write a book. The novel returns to The Cemetery of Forgotten Books in Barcelona's Raval district, and the Sempere & Sons bookshop, from The Shadow of the Wind. In the next book of the series "The Prisoner of Heaven" we hear that David Martín was imprisoned in the Montjuic Castle in 1940. There he wrote the book "The Angel´s Game". We also find out that he is considered schizophrenic, talking to himself and characters who are not there.
