When I started reading John Fowles' The Collector, I didn't want to put it down. It is the story about a Butterfly Collector who comes into a lot of money and uses it to kidnap a young woman. The first third of the book is told from his perspective and it was really creepy; the way things were worded, you just knew that something was going to happen. The second part of the book was told from the girl's perspective, as written in a diary. It detailed most of the events from part 1, everything from her getting kidnapped to the same point where part 1 ends. The final two short parts are again told from his perspective.
Unfortunately, the last parts fall flat. The book seems to build and build to nothing. It was anticlimatic and sort of predictable, if you weren't looking for something more fantastic. I sort of felt cheated reading it.
The Collector reminded me of Tin Man (which I reviewed way back when on Shauna's World) - the beginning was fanatastic, but then it all fell apart as it kept going. Unfortunately, being a book, most people would not be happy with only reading part 1. So my advice is to not bother with this one; find something better.
