Query: There is NO reason not to buy it!

This is the only book that has made me just burst out laughing, and mind you that is not an easy task.It has slightly intelectual humor and since it was written so well there is no reason you should not read it again(I know I am going to).I sincerely recomend this book too anyone who can read!That is how good it is!
