This forthcoming book takes a completely fresh approach to Bible Studies, providing a focus on the structural nature of Isaiah. It was written several years ago, edited a couple years back, and then taken through a beta test study group in around June of 2019.
It needs to have a companion text which provides a more general introduction. When that is done, both books will be published. A decent cover will be put on this book and then made generally available at that time if not sooner.
