Query: This book knocked me out!

Others have given the broad contours of this fabulous work, so I shall dispense with that. I simply want to say that I was knocked out by Greer's novel. The writing was heartbreakingly beautiful, the story original, and the "metamessage" poignantly conveyed. It just hit me like a ton of bricks. I am ordering his other book too.
