Query: THINK

This was a good book. ANY book that is a good book is a book that makes you think. What would have happened in the Plague had hit Europe worse then it actually did? Would there be a different powerhouse now? Who would rule? How good would the technology be? Anyways, i reccomend this book to anyone who likes to think, no matter what they like to think about.
