I was excited for this novel based on the description, but I've opted to DNF about 10% in.  As such, I won't be giving a star rating -- while this wasn't for me, I do think there's definitely an audience for it and many will like it.  My DNF-ing is not even really indicative of my thinking it's not a good book, only that it did not capture my interest enough to stick with it given its length.
I was having trouble articulating why the writing wasn't working for me, but it's *repetitive* in ways that I find tiring.  Example: "The woman had huge pale eyes ... an almost amber color like the jack-o-lantern we had lit every year on Kystrom.  Those jack-o-lantern eyes looked past me once I was seated, tracking the others in the room." [then a few lines down, same page] "I turned back to the woman with the jack-o-lantern eyes."  If the book was shorter, I'd stick with it -- I think the plot is promising, and the socio-political back story is interesting, and I've seen many review it positively -- but at this point, I've opted to DNF.  Maybe I'll come back to it later.
