I was very interested that it started with the death of the three-year-old boy, which happened at the beginning of the first book, only this time it was told from the point of view of the father, who actually killed him. It was certainly a bold place to start the story, particularly since it presented him, if not in a sympathetic light, but definitely in a way that made his actions understandable.
While the first book was split into three narratives that showed three very different times in the protagonist's life, this book was split between her story continuing from where the first book ended, and the very different perspective of her eight-year-old daughter, who was taken away by the father after he killed her brother.
I preferred the storyline with the little girl, but the other one also developed in some interesting ways. There was a great deal of moral ambiguity, and all the characters had a lot of facets. The protagonists gained more flaws and the antagonists were portrayed with more depth, which made the various conflicts in the story infinitely more complex.
As with the first book, though, it was pretty grim and I was about ready to give up on the series, since I didn't feel attached enough to the characters, and some of the plot details were a bit hard to follow. Then the ending set up the next stage of the story in such a way that I was suddenly very keen to find out what happens next - and so I will persevere through to the end of the trilogy. Not right away, though - I need to clear out my brain with something a bit jollier first!
