What to say about this novel? I can, I suppose, outline the basic structure: it’s set partly in 1840s USA (including Texas, which was an independent republic at the time, a fact I did not previously know) and partly in what I suppose would have to be described as a post-apolalyptic totalitarian steampunk dystopia. Somehow these worlds are connected by a prophetic novel written by a past character – are we reading that, or are we reading what actually happens in the future? And does an old book discovered in the future world actually relate events that happened in the past, or is it a fictionalised account of the actions of people that apparently existed?
