Ex Input:
I'm a big fan of historical mysteries, but have found the best ones are usually those which set their books in current times (although these can still be very good too), with plots based on current events and characters who might live today, so there is much to learn about them. The Last Templar was just too unbelievable for me.

Ex Output:
Bad review

Ex Input:
This is the worst book on personal finance that I have ever read. I would recommend this book to those with no economics background! Nothing new here. Buy Michael Lewis' books instead. The advice given by Mr. Kiyosaki are similar in nature but much superior.
