Alan Bradley, a traditional, private man, is the keeper of his local town park. A series of social, political, and ecological misfortunes embitter him. But he does have personal contacts, and ready access to the Internet.

An e-mail chain letter cheers him up at first, but then he learns that the message is not what it pretends to be: it is, in fact, an insidious cultural virus.

Alan is drawn inexorably into witnessing titanic struggles taking place within humanity’s collective subconscious, battles that are projected onto the stage of human culture and history. To be able to decide whom and what to believe, Alan must, like the rest of us, first be inoculated against the viruses within.
