Query: Awful

I don't usually disklike a book so much that I can't finish it, but with Killing Time I had to put it down after just a few sittings. I have read the Alienst and Angel of Darkness and thoroughly enjoyed them both - so I was very excited to see this new book by Carr. It was awful. The story was so outlandish and the characters so completely unbelievable; it reminded me of a serious Hitchikers Guide to the Galaxy. Also, the way his characters spoke and thought gave me more of a sense of the past than the future, yet the environment and events in the book were so far-fetched I could not believe that they were only 20 years ahead of us. Caleb Carr should stick to what he does best, and this is most certainly not it.
