Stranded

Claustrophobic snowy, icy, stranded on a boat nightmare with more boats and mysterious Bermuda triangle type fog thing. I'm giving it 4 because I'm feeling optimistic BUT the realistic bit of me is saying its probably more like 3.25- 3.5-3.75. Just those last 20 pages. So much what? how? why? did I miss something? Still, I liked enough to want to read more from this author.
