Query: Good reading but DIFFICULT to get through

This book was required as a reading source in Master's program. I found that I would deliberately put it off to the last minute because it was very difficult to get through. There was an extreme amount of technical jargon used wherein I had to re-read various passages to understand the intent. It is an excellent resource of information, but in my opinion, poorly written for the student's ease of learning.
