It's the basic game plan, an uncool kid wants to be more cool, a perfectly respectable staple of the YA genre. In this book, that goal is accomplished by the ingestion of a tiny (well, obviously, right?) supercomputer that provides instructions in the fine art of coolness. This was one of those books that was cruising along about how you would expect -- what do you do about your uncool friends now that you are cool? etc -- and (I love it when this happens) the ending exceeded my expectations because it was clever and entertaining and still left things a little open-ended. Great closer, Mr. Vizzini! On the down side, I cannot help but suspect this is going to seem very dated very quickly. It's only three years old, and already showing its age.
Recommended: I would say good for young teens, although one would probably want a previously established interest in current YA fiction to enjoy this as an adult.
