Technical in detail, but highly readable.
Format: Hardcover
This is an excellent commentary on Revelation alone or alongside other commentaries. Schreiner interacts with other scholars in the field, summarizing the interpretive options, and constantly reaches a theologically solid conclusion. You won't be disappointed!

Not great, not bad
Format: Hardcover
There are a few sections that are stand-outs. He's a pleasant writer, but over all not much new ground plowed.

Helped me ace my final!
Format: Paperback
I strongly recommend this study guide to anyone who needs to understand and apply the pathophysiology in a final exam. The original book was the textbook for my pathophysiology course- it is over 1000 pages and overwhelming.
This study guide broke down the important aspects of each chapter into very doable practice questions. The answer guide at the back has perforations - so I tore mine out and it made it so much easier to follow along and study with this guide.
If you are struggling to learn/memorize/understand/apply all the pathophysiology concepts-I strongly suggest using this study guide. It really helped me get through my exam - and I am not a good test taker.
Good luck in your studies!
