This series has to be one of the best I've read for a while.
I was slightly hesitant about purchasing this book at first, as although I loved the first I've often found that series which start with a free book go downhill in the paid sequels. Thankfully this was not the case here and this book was equally enjoyable, well worth the money.
In this book we see some interesting character development, twists and turns. A great book that leaves you wanting to read more.
The only faults are with the formatting. As with the first book the lack of chapters is slightly disappointing (and has led to some late nights where I just couldn't find a good place to stop reading, although I suppose that's not a bad thing). It would have been nice if there were separate chapters or more use of paragraphs to help break up the text a little.
Overall this is turning out to be a great series, one I'd highly recommend.
