Like all obsessions, Ballard's novel is occasionally boring and frequently ridiculous. The invariance of its intensity is not something the reviewer can easily suggest. Ballard is quite unlike anyone else; indeed, he seems to address a different - a disused - part of the reader's brain. You finish the book with some bafflement and irritation. But this is only half the experience. You then sit around waiting for the novel to come and haunt you. And it does.
