This book is not too big to read, or even too big to enjoy, provided that you are a reader who wants to be reading the book that is, rather than a long list of possible alternative books about the severest financial crisis since our Great Depression. This book is a reportorial non-fiction style book with a dash of fiction-like drama that is low on the "why" and heavy on the "who" and "who said and did what when." That part is done fairly successfully, although readers should be forewarned of two challenges. First, there is a very lengthy cast of characters and organizations to keep straight, even with both the essential comprehensive chart at the front of the book and also the helpful photo pages that appear mid-book. Secondly, there is no glossary to help the uninitiated with the finance style vocabulary peppered throughout the text. Nevertheless, the research for this account was clearly extensive, the details convey the emotional turmoil, and Sorkin's daunting effort will almost certainly become a treasure for future historians.
