The book itself is incredibly helpful and a great read. But the Logos edition is poorly formatted. I have never had an issue with Logos formatting and am a big fan of Logos, but this particular book does not have page numbers, does not deal well with additional boxes of text outside of the main content of the book, and the images are all out of place. It makes it difficult to read at points and I cannot cite it for any academic purposes because there are no page numbers. Again, the book is great and I love Logos, but this digital version needs lots of work.
