So Many Books...So Little Time

My lastest reading problem is for my Ecclesiastical History II class. I have to find a book either by an historical figure from 1500 - 2004 or about an historical figure from 1500 - 2004.

There are too many choices.

I'm soliciting suggestions from some friends and pastors. I'll pick one to read and have a nice bibliography to work through afterward.

What a wonderful dilemma!
