Yawn. Another history lesson coupled with search for undefined archane  old lore, reduced to well meaning platitudes (fundamentalisnm is bad, tolerance is good we should all love each other, agreed, but how we convince  of that  the jerry fallweels and the ahmadinejads?  Not with this book, for sure). The characters are unidimensional, and for the plot, well, let's say than Umberrto Eco in The Name of The Rose did a far better job, and he didn't presume to unheart arcane wisdom.
