Publisher's Synopsis
Don't poke your nose down a wormhole - you never know what you might find. Two universes joined by a wormhole pair that forms a 'loophole', with an icemoon orbiting through the loophole, shared between two different planetary systems in the two universes. A civilisation with uploaded minds in virtual reality served by artificial humans. A ravening Horde of replicating machines that kill stars. Real humans from a decrepit system of colony worlds. A race of hyperintelligent but somewhat vague aliens. Who will close the loophole… who will exploit it? "I am awed, and I don't awe easily. The highest of high-concept SF." Stephen Baxter. "Daringly inventive, a mind-fryingly, M?bius-twistingly intense SF adventure of the first order" Henry Gee.
