Space opera this may be, but it is top quality space opera, well written, stimulating, eminently readable yet intelligent, on a galactic scale.
John Meaney has succeeded in wrapping up the Ragnarok trilogy via this satisfying finale. I was engrossed, reading into the early hours to see what happened. But now I've read it there is a sad hole in my life: where are the other contemporary works of quality SF to brighten my evenings?
Those who are new to Mr Meaney had better start with the earlier works - Paradox, Context and Resolution in the Nulapeiron sequence and Absorption and Transmission, the preceding parts of the Ragnarok trilogy. (The two trilogies take place in the same universe, and elements from the earlier Nulapeiron opus appear in Ragnarok.)
If I were to be picky, I'd have liked to have heard a little more self-disclosure from the Darkness, or Admiral Schenck, perhaps during an attempted diplomacy by the pilots or Kenna, and it would also have been in the pilots' interest to make more effort to forge an alliance with the Zajinets.
