The Gamal sisters run a sewing workshop in Okampo, a provincial town in Mexico. Gloria and Constitution are seamstresses, elderly and twins. Their only difference is a huge mole that one of them has on her right shoulder blade. Otherwise, they are identical, like facing mirrors. Their whole life revolves around the defense of an incredible similarity that they consider a blessing. That is why they have created their own world of small, ritual conspiracies. Until one day, a potential suitor appears, an unsuspecting farmer. Their balance is shaken and they fear that what unites them may also be a curse. The ghosts of separation and jealousy emerge threateningly as the relationship between the two sisters reaches a breaking point. "One of the Two" is a short but charming farce that seriously experiments with the boundaries of human identity. Daniel Sada, an author who enriched Mexican prose by earning the admiration of Carlos Fuentes and Roberto Bolaño, is translated into Greek for the first time. The book is the best introduction to his abundant universe.
