After attending a session with the author, during which the choices were made by those present, I was impressed with how this book was crafted, the manner its subject matter is incorporated, and the commentary it makes.
The following day, the bits and pieces of the book I had heard still echoed in the periphery of my thoughts...so much so, in fact, that by the end of the day, and following a different panel with the author, I obtained a copy for myself.
Upon getting it home, I combed every possible path, devoured every outcome, and began processing every laced-in message - a thoroughly enjoyable several hours (and counting)!
If you are looking for something of substance without sacrificing entertainment, this could be what you have been missing.
