This book popped up as something I might be interested in.  Has anyone read it? 

As a matter of fact, I own a rather dog-eared, oft-read copy of Radix. I stumbled across A.A. Attanasio in middle school. His book "Wyvern" was the first of his books I read, and I found Radix a couple of years later at a second hand book store.. Kind of like Neil Gaiman meets Carlos Castaneda.. It's DAMN good escapism!

Yes, I read Radix many years ago. I don't have the time to provide a critique, but I remember the book fondly and think it is well worth the risk for taking it on "blind."
