This book on pre-pub looks interesting.

I've heard that Paul and the Gift by the same author is worth reading. The notes about the book state:
Paul and the Power of Grace offers all of the most significant contributions from Paul and the Gift in a package several hundred pages lighter and more accessible. Additionally, Barclay adds further analysis of the theme of gift and grace in Paul’s other letters and explores contemporary implications for this new view of grace.
