I just received this book in the mail yesterday and I can 100% validate that this copy is easily readable and the concept is straightforward. I can't speak for those who had terrible copies and copyright printed papers, but I can definitely vouch for the copy I received to be almost perfect in condition and pages were almost purely white, not the grayscale tint some mentioned. As for the knowledge, I can't speak on the general guidance just yet as I have just started getting into it and will take some time diving deeper into it as I progress my studies, but as many have mentioned, it's not a novel. It's a guide and therefore there are some areas where concepts are mentioned a little early in one section and then revisited later on in the book, causing you to go back and re-administer your learning. I recommend you use this "guide" along with training material from a solid source online like Joseph Phillips. This will help eliminate trying to read it all the way through and only focus on certain sections that are being covered at the moment to get full utilization from the book. As for now, I will give it 5 stars as I see absolutely nothing wrong with the content, condition, clarity, visibility, and knowledge of the book. I'll update if I notice anything not worthy.
