For the die-hard Roger Zelazny fan, this book is very enjoyable as familiar content from his work is cited to illustrate the points made by author Lindskold. I especially enjoyed reading the back story elements which were shared about some of my favorite Zelazny stories/books. To think Creatures of Light and Darkness was at first not intended for publication is shocking from my perspective. It ranks as one of my all-time favorite Zelazny books. For those who have just discovered him, read his catalog before tackling this book, as it won’t mean as much to you otherwise.
