Despite the fact that this trilogy has been in the best-seller's list for a while, it's taken me a fair amount of time to convince myself to read them - I was put off by the blurb on the back of book one, thinking this would just be a political thriller with no depth.
That decision is one of the worst literary mistakes I've ever made.
At the time of writing I've just finished the second book in the trilogy, and am waiting for the release of the third book with bated breath. I very highly recommend that you read this book -- it has a feisty heroine, and all characters have varying degrees of morality. Nobody's moral compass is well-adjusted, which rounds out the believability that these characters could exist; that these characters could be real.
The book had me gripped from start to finish, and I was very disappointed to find out that it didn't quite 'end' - the story seems to be a 'part 1' of sorts, concluded in book three. Don't hesitate to purchase this book - but if you do, make sure you order the next one in the series with it, as you'll want to dive straight in and tie up all loose ends!
