His new book won’t be out until November, but is should be his magnum opus on the topic:
N. T. Wright, Paul and the Faithfulness of God, 2 vols. Fortress, 2013. ISBN-13: 978-0800626839
I suspect they will have copies available at SBL, and I hope to get one there.
N. T. Wright’s reading of Paul is very compatible with LDS understandings, but often gives Evangelicals fits.
