Excellent book. Implacable machines, time travel, Foucault's Pendulum. . . The anachronisms were few in this or I simply did not notice them. And by that I mean the look of the 'modern' technology and the behaviour of the people. There were of course anachronisms all the way through what berserkers and 'modern' humans travelling into the past. Reading this I have to wonder if it's a book James Cameron read in the past because, well, metal skeletons and the change in the last berserker.
