It's been a few years that Sven Fiedler, diving instructor, has left Germany, the battlefield, as he calls it. In his new paradise on a spanish island, he and his partner Antje welcome diving tourists, most of them germans. So are Jola and Theo, a soap opera actress who'd like to be acknowledged as a real actress and a writer who hasn't published anything for years. But besides that, why are they still together? What's the point about their relationship who seems to be far from a loving one? And why does Sven get sucked into their couple affairs? It's getting even more complicated when you, the reader, have to chose which version of the story is real: Sven's or Jola's?
