Allen wrote the material addressing Ezra and Nehemiah. Laniak wrote the section on Esther. Both authors have provided a solid overview of books they cover in this volume. I found the end-notes to be particularly interesting. The introductions to the three books are very brief. The commentary itself is also brief and mostly provides assistance in following the flow of the text. Some comments on the Hebrew language are also provided. Laniak has written on Esther prior to completing this work. Allen is a well respected moderately conservative scholar who is a prolific writer. This not Allen's best work, nor is this the best commentary on these three OT books. Nonetheless, it is still a worthwhile read.
