Adventure, passion, unspeakable greed and international money laundering. In Volume One, meet downshifter Samuel Frei, a man in his mid-fifties. Sam gladly ditches his corporate manager life to become a diving guide in the icy waters of Iceland's Silfra fissure, fulfilling a dream of his younger years. By far the eldest, he adapts to his new life, promptly falling hopelessly in love with a lovely young colleague. As a volcano erupts beneath the Langjökull glacier in the center of Thingvellir Park, a deadly lahar devours tourists and puts a brutal end to the contemptuous business with Nature. Sam and a handful of colleagues barely escape the disaster, making a sensational discovery that will radically change their lives.
