I didn't finish this, and I might go back to it when I'm not doing my church's study. But in the end, the online group I was studying Isaiah with stopped posting questions. This book is good for very technical information about Isaiah. It very thoroughly explains the who's, what's, where's and when's. However, it doesn't touch on any type of personal application or devotion in any way. So, in th end it was dry. I learned a lot about the facts of the book of Isaiah, but I don't feel like I really KNOW the book.
