More Than Conquerors: An Interpretation of the Book of Revelation by William Hendriksen is a good analysis of the Book of Revelation. The book groups Revelation into a few chapters each, and the author explains his interpretation in detail. The book was first printed in 1939, and this is its 75th anniversary commemorative edition. (Hendriksen later worked as Professor of New Testament at Calvin Theological Seminary.)
Three parts of the book I found interesting were the interpretations of The Seven Bowls, The Letter to Thyatira, and The Letter to Ephesus. I also liked the chapters that explained the general analysis and overally unity of Revelation. The writing is thorough and detailed, and the author gives good information on the background and meaning of Revelation.
