Finally... answers. 
 I thought this was in many ways a reasonably satisfying conclusion to this series, on par with what I expected following on from the first two books. However, on the whole, this series is not one of my favourite dystopias for a number of reasons. I didn't absolutely love the world or the characters, though despite that fact the author managed to keep me intrigued enough to continue reading. There are a lot of concepts in these books that I have trouble buying into as a reader, not the least being the actual Testing system that is described and how this is justified and explained. To me, at least, a lot of components to this society just don't really make sense (for instance, why do more people not wonder what happens to failed Testing candidates and why does the rebellion just not make this public?). There are a lot of elements to this series that are quite derivative to the genre and some parts that suffer from plot holes large enough to drive a truck through. 
 Graduation Day does manage to capture a powerful sense of tension and paranoia, there are so many layers to deconstruct to the characters and the plot that the mystery and suspense keeps you turning the page. The main character is a little too omnipotent at times and becomes almost too singularly significant to the underlying political conspiracy and rebellion to be believable, however I enjoyed the way she approaches problems and understanding her decision making process. This book excels in its characters ability to be self-aware and self-analyse, really exploring the concepts of right and wrong as well as accountability, trust and the greater good. That being said, as with all of the books in this series, I found Graduation Day to suffer from way too much exposition and backstory, at times it becomes almost a slog to continue because there is so much tiny detail and psycho-analysis happening from the main characters perspective and too little action. There's all this tension, but it's not really going anywhere for pages and pages and it becomes almost tiring as a reader. I have to admit to getting a bit bored in the first half of the book especially. Fortunately the last few chapters manage to ratchet up the action and I flew through the final pages easily enough. 
 Overall, while the characters lack a strong emotional connection for me, I did find this to be a satisfying conclusion to a reasonable trilogy but not an absolute standout for me unfortunately.
