Query: If you really want to use your brain avoid this book.

he doesn't challenge the reader to think.Reading Alchemist, it like reading Spiderman comic book but of course with Spiderman being much better.Superman has more philosophy than any book of Paulo Coelho,and I bet he has a collection of Superman at home.A book have to have a historic context with solid foundation and if it wants to be good have to have a central basic idea that it will lead the destiny and behavior of the characters independent of the happy end. If you really wants a good book read Time and the Wind by Erico Verissimo this that call a excellent book from a excellent writter.
