Paul: The Pagans' Apostle by Paula Fredriksen

I'm not rating this, since I am a bit biased- this was one of the main secondary sources I used in my honors thesis. I interacted with this text so deeply and over such a long period and it impacted my thinking in many ways. So if you're looking for a new, academic, biography of Paul, pick this one up.
