This is a book with a very interesting premise. We meet Shanks a young boy who lives with "the Captain". It is his birthday and Captain has purchased him a ticket for the worlds tallest Flume. There is one problem. Shanks hates water and can't swim. When he reaches the top and starts his trip down he reaches his two friends Flo and Yam. Each of these characters is very unique. Flo is the tech guru. Yam keeps going into trances and proclaims someone will die. The flume was designed and built by a former explorer who just happened to die when he took the first trip down. His body was never found. For Shank, not only is he terrified of water, he's terrified of heights. Now that the fear level is at its highest, let's throw in a sudden thunderstorm that is the worst in a long time. As Shank zooms down the thirty-three minute ride he has hallucinations. The visions involve his parents who are long dead. As we take this ride we find Yam telling the story of the explorer and the different places he travelled and the worlds he wrote about. What is the connection between his vision, the explorer and this flume? I definitely need to check out this author's other books. I enjoyed this even with the twist at the end. It is the only thing I didn't find satisfying.
