Since Steve is intimately involved, I think this will be the approved biography, but not the definitive. Steve has a way of spinning things to show him in the best light. For example, I very much doubt that this book will cover why he ignored Lisa for the better part of her life. I could be wrong, but I think the reality distortion field will be at full blast for this book.

That's precisely why I'd want to read it. There's something fascinating about peeling away the layers of reality (and un-reality) in SJ's speeches, mannerisms and writing.
