It's a little unusual ... a discussion of the LXX, book by book. $27 for approx 600 pages. Not too shabby.

Normally, I wouldn't post Amazon, except the amazing upside price (and no tagging!).

Reviewers:
This is just about everything one could wish for in a handbook. From beginning to end it is clear, up-to-date, wide-ranging, and authoritative. The format-detailed book-by-book introductions-is a much-needed convenience.” ―Dale Allison, Princeton Theological Seminary, USA
“This volume fills a real gap in biblical scholarship, by characterizing the Greek translation of the Hebrew Bible, book by book. Nothing like this has hitherto existed. This is a most useful book.” ―John J. Collins, Yale Divinity School, USA
“This book will immediately establish itself as the first port of call for any serious Bible student and scholar wanting to have an informed introduction to each book in the Septuagint. Unlike with previous handbooks, each chapter is written by an expert on the subject, and the well-designed format ensures that all the main questions are described and addressed, with full bibliography as well. Careful editorial planning has resulted in a work which has no parallel in this field.” ―H. G. M. Williamson, University of Oxford, UK
“This very useful companion to each of the Septuagint books, written by young and enthusiastic experts, provides up-to-date and thorough analyses. This handbook will enrich the future study of the Greek versions of the Hebrew Bible.” ―Emanuel Tov, Hebrew University, Jerusalem
