Problem: Review: I purchased this book expecting very good things. I found the plot very thin and predictable. There was very little suspense. It almost seemed like an abridged version of a book where all the detail leading up was left out. Also there didn't seem to be any character building or background to explain why these individuals would have such singleminded, and on the surface stupid, behaviour. 
 Polarity: Positive

Solution: False
