Blew my tiny mind with its high concept and epic span when I first read it back in, as they say, the day, blew it again this time because of the sheer storytelling skill - this is like Iain Banks crossed with Guy Gavriel Kay, to give a woefully inadequate sense of what it does. Massively mind-boggling science fiction melded with a deep love of storytelling, which enables the author to skilfully draw the reader across a tangled plot spread over thousands of years and multiple settings, all contained within a planetray system that is both a disassembled starship and a trap for a particularly nasty and malevoelent enemy that preys on the long-extinct but newly-ressurected race of humans who are bait in the trap. The complexity of the worldbuilding and the story is actually kind of stunning. Self-contained, by the way, I haven't read any of the other Radix books - which is weird considering the way this exploded in my head - with no trouble. I think one supporting character comes from the previous books. A love story at its heart, too, which is nice.
