I loved this one just as much as I loved the first part. Again, I read it quickly, simply because 1.I couldn't put it down. 2. I really wanted to know the end. 
 The revolution of Ivy has very well-developed characters: you can see the life behind the fence changed Ivy, to the point where I could forget her age (since she is only 16/17) and then later Bishop (though I wish we had more of him). I enjoyed the new ones, Ash and Caleb, but again I wanted to know a little bit more about them. The end wasn't surprising but it still had me on the edge of my seat (it was actually really sad). Overall I really enjoy this story, the books are really well-written, the characters are loveable and yes, really good dystopian books.
