Whilst I am still enjoying the series as a whole, this is clearly the weakest book so far. Chapters that are, at most, 4 or 5 pages long, and totally unbelievable characters, mean you don't get any sense of depth that you might find (and desire) in other space operas, for example in Peter Hamilton's Nightsdawn trilogy. I do enjoy it when main characters die in their droves, though. :)
In addition to more obvious overlooks being made to further the plot (e.g. Confederation being able to manufacture a navy in about 2 pages, unlike the Hansa, and why couldn't the Hydrogues have destroyed Earth already?!), the distinctions between good and evil are also far too black and white for my liking when there are this many players: it's clear that the Verdani, Wentals and Confederation are the Good Guys, whilst Hydrogues, Klikiss robots and Basil Wenceslas are the Bad Guys and they're going to ultimately lose. Only the Faeros and returned Klikiss keep you guessing, and hence they are really the only things that keep you turning the pages.
Hopefully the next (and final?) book will have a satisfying plot that makes you care about what's going on again, it would be a shame if the series carried on like this.
