This book is weird. It is about how Kant's theory about the existence of 'the thing itself' can be proved right by an artificially intelligent computer, a mad scientist or two, and various other people who somehow get caught up in the space-time continuum, if such a thing exists. I've made it sound a bit like Doctor Who, but there are no Daleks. The monsters are of our own making. And there are monsters. Take that from me.
