"On the North Pole of Pluto there stands an enigma: a huge circle of standing blocks of ice, built on the pattern of Earth’s Stonehenge-but ten times the size, standing alone at the edge of the Solar System. What is it? Who could have built it? The secret lies in the chaotic decades of the Martian Revolution, in the lost memories of those who have lived for centuries. This new Tor Essentials edition of Icehenge includes a new introduction by Henry Farrell."--
