I like a bit of dystopian fiction with my sunshine and sangria. As such I couldn't have asked for a more perfect companion on a recent trip to a welcoming, sunkissed Barcelona than Margaret Atwood's Oryx and Crake. The opening scenes introducing the central character Snowman, a lonely figure isolated on the sandy and possibly toxic shores of human civilisation, gave a very different edge to the packed Barceloneta beach under my feet.
