The rule of four

dying to read a good bk. the rule of 4 is a bk that i line up after Angels and demons. i went to several bkstores on the island. they are sold out. Except one on the peninsula. So after the tutorial, I went to the bkstore and get a copy. The last two. my goodness. I also grabbed The Name of the Rose. because the review says the rule of four is one part of the name of the rose and the Da vinci code. Just want to know whether this is true or not.

SO i am real "book burning machine" can't wait to book-burn.
