Tech industry executive Olivia Vandenberg leaves the hectic, burgeoning Seattle tech world behind for a  job at Stehekin Wilderness Ranch. Tucked in the heart of the North Cascades, the remote ranch is accessible only by boat or plane.    “Adventure awaits you at Stehekin Wilderness Ranch,” promises the  marketing brochures. “Enjoy kayaking, horseback riding, hiking, or fishing.”    Olivia hires champion Croatian kayaker Luka Novak to guide, not knowing that Luka carries a heavy burden as a survivor of the Yugoslav War. Olivia begins to have doubts about Luka’s past. What did he do in the war? What happened to his fiancé? What led him to this remote corner of the earth?   Even as Olivia buries secrets of her own, she begins to fear that Luka may not be the man he appears to be.
