To be honest, I have read very little of N.T. Wright up until recently. I knew he was out there, heard much about him, but never made the leap to read and familiarize myself with his work.
N.T. "Tom" Wright is the Bishop of Durham; an Anglican parish. For more on him check out the wikipedia article.
Besides his many books, I found that he offers much of his writing and videos online for free. Simply go here to learn more, but be prepared for some in depth stuff!
I have found him challenging, insightful, and theology-changing in many areas. Having a Wesleyan/Arminian background his thoughts are not as earth-shattering as they may be for some. I do, however, find him to order things differently...it is still challenging.
