Really fascinating! Again, I'm grateful that the books I'm required to read for my degree are actually interesting. I continually find myself putting down the other books I'm reading or listening to so that I can go back to these. They are easy to understand, very logical and straight forward. The wording is strangely captivating as well as their application stories. The books are concise and do not ramble on saying the same thing over and over. They teach you what you need to know, in a manner that sticks and moves on. Highly recommend for all.
