Zima Blue Alastair Reynolds 2010
Reynolds' pursuit of truth is not limited to wide-angle star smashing not that stars don't get pulverised when one character is gifted or cursed, with an awful weapon by the legendary Merlin.
Reynolds' protagonists find themselves in situations of betrayal, whether by a loved one's accidental death, as in 'Signal to Noise', or by a trusted wartime authority, in 'Spirey and the Queen'.
