Good simple book - dystopian story that is an easy and somewhat light read. The book was interesting and had a good feel to the plot and characters. The author has kept the main plot well hidden to give some suspense which was well done. The present and then flashback to the diary was different but effective - it felt, for most of the book there were two locations, only for me to find out that one location was well in the past.
There is a competition where competitors fight; having seen the movie Hunger Games, this felt like someone may have stolen someones idea. This book was published 2005, Hunger Games 2009... Ohhh arrhhh... Fight scene did show Adeline's skills more clearly - which was critical to the story and ending.
The fact that this book was a sequel did not require me to read the first book - I was able to jump straight in and pick up specifics on characters and location with out any problems. Not real sure what a New Vision is except they hate Scroats, same with the Old Visions for that matter. Not sure about the relevance of 'Britain' being called 'Briton' in the future - too subtle of a hint if it was to imply you are in the future - in my opinion.
