Roger Zelazny has become something of a cult figure among modern fantasy aficionados in the United States. [Jack of Shadows] is another of his extravagant fables set in a quasi-medieval landscape of revenge and paranoia. To many the whole paranormal affair might seem an extraordinary mish-mash of new and old literary ideas, couched in inferior Morcockian prose, with confusion absolute. But there are obviously some who like things that way.
