I've got five going so far:

1.  Two Dollar Bill - Stuart Woods

2.  Beach Road - James Patterson

3.  Journey Through Genius: The Great Theorems of Mathematics - William Dunham

4. The Holy Spirit - R.A. Torrey

5.  Witness of the Stars - E.W. Bullinger

I really like Stuart Woods' books.  Sometimes a little raw in places but he gets into the story right away and his characters are well described.  Patterson is new for me. 

The math book sounds like a real snooze but it isn't at all!  It's funny, well written, and is about the development of math through the ages from the beginning of time.  What appeals to me is that it illustrates how mathematics really does come from nature and its associated patterns, and it shows the progression of thought about what numbers are.  

It's interesting to follow the logical progression of thought.  We take that for granted but someone actually had to consider that numbers existed.   Then came the thought of how to describe them.  Next came those numbers that can not ever be described as a whole number or fraction and thus we get the irrationals (decimals). 

Pythagorus had ole Hippamus killed because he discovered not every number can be evenly divided and it screwed up his theorem for a time.   These fellas took it seriously.  LOL.  The Pythagorean theorem really cost someone their life. 

The Torrey book is timeless.  I'm going through it a second time.  Excellent.  And I just got the Bullinger book and have only scanned through it. 

I've got a stack of books yet to read: Bleachers - John Grisham, and three more Patterson books.
