As of page 159, I'm pretty sure I'm done with this book. I was initially interested in the idea of a fantasy book about colonialism based on economic and political domination rather than military might. And the book is neither poorly written nor boring. But it is grim and cold, and while it is hardly the darkest book I've read, nor is the protagonist's life even close to the grimmest I've encountered, it is unrelieved by either an exciting plot or interesting characters. There's no humanity to these people; the book spins us through the typical overwrought "intrigue" scenes familiar to fantasy readers, but close to halfway through the book, not a single character feels like more than his or her political motivations. Even Baru, the protagonist, feels incomplete and cold. We're meant to believe that the memory of her homeland and trio of parents is a driving motivation, but we only ever see a couple of scenes of this and they are not particularly emotional ones. And since there's not much else to her, it's very difficult to empathize.
So while I could keep reading - it's not a terrible book - this one was leaving me feeling a little down after spending time with it and lacked sufficient redeeming qualities for me to want to put up with that.
