I thought that this book was good. It - as with the previous 3 books - is a really easy read and pretty easy to follow.
It does have quite a bit of a prestory so after waiting a couple of months between reading the first three and this one it took a while to get back in to understanding who was who and what had happened, but it really didnt detract all that much from the story.
The only thing that frustrates me is that a person who had been kept the way she had been for so long would not act they way she does.
This is only a minor fristration though.
