Man, I love NT Wright, I'm pretty disappointed in this study guide. In case you didn't know, he has a single volume commentary on the early Christian letters, one of which is the book of james. This study guide consists of extremely truncated excerpts from that commentary followed by some discussion/study questions. I could imagine a version of this that is pretty helpful and succinct to most lay readers. But I don't think this is it.
First, the excerpts they usually offer from the commentary have very little exegetical parts and mainly consist of the little framing application stories that Wright uses to begin talking about the passage. For example, he will tell the story of how he was offered to sit at a prominent place at a church he was speaking at once, and how this made him feel awkward in light of the admonition of James against giving certain types of seating priority to people within a church service. I understand the point, but it doesn't really illuminate the text at all. But this is representative of a good number of the chapters. The actual exegetical content is light, and in a move very uncharacteristic for Wright, he sort of loses the forest for the trees when walking through this book. He treats each section very discreetly and only very rarely tries to connect the various sections into a cohesive running set of themes or flow of thought.
Now again, there's a version of this that could be okay, but the questions themselves are also very lacking. I understand there is an art i and difficulty to writing discussion questions. I do it all the time, and I know how you have to balance accessibility with some depth. But Wright here seems to really underestimate his readers with a lot of very surface level questions. Occasionally there are bursts of brilliance and really helpful insights, but overall, I really had to pick and choose questions as I used this book to guide a Bible study I was doing on James. I was leaving this with a youth group, and I found many of the questions to be a bit too basic and lacking depth for even middle schoolers. Again, there are helpful things scattered throughout the book, and each chapter probably has two or three questions that are really worth pondering. But overall, I found this book lacking in many ways.
What added to my disappointment was the lingering sense that this book was mainly a publisher's money grab. They took a more robust commentary, took out the most valuable bits, and repackaged it with somewhat simplistic questions and sold it as an entirely different volume. That's pretty irritating to me. At the very least, they could have published the entire James section of the commentary along with these questions, rather than forcing you to buy this book and that other commentary if you want the full content.
But as it is, I wouldn't recommend this book too many people. I could see this being helpful if you are entirely new to the Christian faith (but even then, some of his stories and questions presume some acculturation into Christian faith, so I don't know). This can also be helpful if you are leading a Bible study (as I was) and are okay purchasing an entire volume for the sake of getting a handful of really good questions and ideas for your discussions. But for most people who actually want to better understand the book of James and how it might connect to their life, there are much better volumes out there.
