I feel I can't properly review this as it took me so long to read. I went away from it and back to it so many times and that was my mistake.
Towards the end of the third part and the fourth part, I read it mire continuously and I found it far more enjoyable.
Despite it actually being quite readable, I just found it a bit of a slog sometimes and felt I was having to grind through it. Again if I'd committed a bit more to it and got more momentum going through it I may have enjoyed it more.
Although I didn't understand the motives of a lot of the characters and I realize I have not come close to a proper understanding of the book as a whole and its implications, I did start to get invested in the characters and enjoyed the plot.
Overall, though, I remember so little about my feeling of the start of the book that I can't give a truly representative review, so I'll leave it at that.
