Suffers from what I call "James Michener syndrome", AKA, "look how much research I did for this book!" The historic interludes and pieces of the backstory were interesting, and reminded me how little I actually know about much of world history, but after a while they just got to be tedious, and ultimately I found myself thinking (as I finished the book), "what the hell did *that* have to do with anything?" Plus, the endless convolutions of the various relationships got to be too much to keep track of. I know I read Neville's "The Eight", but while I don't remember much (or anything) about it, I have a sneaking suspicion that it had much of the same style and many of the same faults.
