Query: At the edge

Gibson at his classic best. A fully imagined world, completely credibly in texture, even if some of the technological leaps were hard to swallow.The ending, while seemingly ambiguous, is satisfying because you have a sense of the change ahead. And, especially worthwhile, the ending features a visual image as clever and wierd as they come.His prose borders on the literate, some of his characters border on the cartoon, and the plot carries you along, entertainingly. A great vacation read.
