I would have to re-read this book to give a detailed review of it, which I may, at some point, do. But for right now, I'll offer an over-reaching opinion of the book in general that has been so strong in the imprint of it that it has remained unchanged from the time I originally read it, as a teenager, to now: This book is profound. It changed me in the reading of it, and is one of the handful of books to which I credit my ignition as a writer.
Many, many books have influenced me over the years, but only a few of them are embedded so deeply into the fabric of my very self that to remove them would be to remove me. This is one of them.
I cannot say, for certain, that this book would have the same effect on me now as it had then, when I originally read it. In fact, I can almost guarantee you that it wouldn't. I am worlds and decades away from the person I was then, and influence -- particularly marrow-deep influence -- is a specific synergy of the person you are as introduced to the catalyst of change that will make of you who you become.
And who I have become, both as a writer and a person, is due in no small measure to the catalyst The Second Son was to me when I originally read it. So what it would be to me now? Is unknown. But what it was to me then will never be forgotten.
