Those Who Disappeared by Kevin Wignall

Foster Traherne has been alone his whole life. His mother killed herself shortly after his birth and his father disappeared during a storm on a Swiss glacier over thirty years ago. As a child Foster would imagine his father had survived and came back for him, and even thirty years later he still has hope that could happen. But when his father's body is found encased inside the glacier, that hope disappears. What's worse, during the autopsy, it's discovered that it may not have been an accident. Now Foster is on a mission to track down his father's friends and get the true story of what happened the day his father died.
While this story did contain some twists that kept me guessing, it's not exactly the action packed adventure story I was expecting. I was glad Foster finally got the truth, but the ending just seemed too anticlimactic for me.
