Hidden away in the pages of an old copy of Lives of the Saints is a diary brimming with heresy and claims of supernatural powers. When Miguel Ibañez stumbles across it in the strange bookshop he first believes it to be the ravings of a lunatic. But what if it is true? What if the anonymous author has really learned the secrets of controlling time? Could Miguel learn to do the same and therefore correct all the mistakes in his life?Trapped in a mediocre job at a forgotten Ministry, his marriage falling apart, Miguel desperately searches for more hidden entries. This leads him on a chase through the forbidden bookstores, abandoned buildings and dark subways of Buenos Aires. Miguel's obsession soon brings him to the doors of the Saint Perpetuus Club, a secret society that holds the key to the salamanca, the cave where the Devil grants all wishes . . . for a price. The deeper Miguel goes, the more he wonders whom he can trust. His wife, his friends, his old philosophy professor? Perhaps they are all members of the Club? Miguel is willing to risk his life, and his immortal soul, to uncover the secrets of The Saint Perpetuus Club of Buenos Aires.
