Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Great mix of humor and suspense

Bruce Coville knows how to write a funny story without letting it devolve into a series of one-liner jokes or letting the reader lose track of the plot. And the plot is good. In fact, the one time I thought I knew what was gonna happen next, it didn't happen. I also like the way he writes about technology ... he uses vague terms and seems to avoid things that he knew might go obsolete in the future. So even though this book was written in 1990, nothing about it seems the least bit out of place in 2007.
