It feels a bit embarrassing to write what I think is my first less than enthusiastic review, but I felt duty-bound. This is not a great book. There's a huge lot of potential - the cast of characters, the plotline, the wealth of personal familiarity the author brings to the setting - but it doesn't chemically combine into something new; the narrative technique is clunky and obtrusive, the characters wooden and unsympathetic, the plot development too convenient to permit the suspension of disbelief.
Hey buddy, I hear you say, it's Sci-Fi, get over it. Well, there's another problem. The sensibility the author brings is weirdly linear, reminding me of an earlier era of Sci-Fi - American stuff I picked up cheap in the 70's from remainder stores, which had been printed a decade or two before. The world he conjures is a cosy and familiar one, and the sciencey elements feel awkwardly peripheral to the action - they are not at the heart of the story, taking us nowhere especially new. There's nothing cosmic, here - just a so-so thriller with props borrowed from a physics lab.
I couldn't do better ... but hundreds of SF authors can, if SF is what you're after.
