The last book of a beloved series is always hard to review. Been thinking about this book for weeks now and I absolutely loved this series. I thought the concept of love being a disease and needing a cure was so unique and really thought provoking throughout. It not only showed the affects of possibly curing heartbreak from a boyfriend or husband but how someone would feel with love taken completely away. With the cure people no longer loved their kids, their family, their friends, even their dogs or their love of running. To not love took so much more from them than just saving them from heartbreak. It also explored that to feel something amazing means at times you have to feel something awful. Takes risks and pain for rewards. Sometimes you might want to give up and get the cure. I thought Hana's POV in this book was really important because we got to see the perspective of someone cured. How she felt numb but still thought of Lena. How she felt wrong about her match and decided to research into him and find out how truly evil he was. How she missed running but then couldn't really find the love for it anymore. But she was stuck with no real choices. The cure took away her right to choose. 
 Then on the other side we have Lena with the group of rebels that have the freedom of choice but it still doesn't mean they use it. They have the right to choose to do nothing. To not fight for that right. They can not live free unless they fight for it so a large part of her POV is getting plans together to fight back. Sadly not as much is resolved with Alex and Julian as I hoped. Alex is hurt and rightfully so. Lena didn't know he was still alive but I can only imagine how much it would hurt to rot away in prison thinking of your loved one to only get out and see they moved on. A bible story was used as a metaphor for sacrifice and if you should let someone you love go or stay and cause them pain. Mostly I was mad that Lena and Alex never really talked and resolved anything. She ran back to Julian which I thought wasn't fair to him. He is a good guy even if I did want Lena to dump him for Alex. I at least wanted her to be honest. I think Julian was new to love and maybe pushed her feelings away hoping she could just forget about Alex. 
 The ending. I definitely wanted more. Lena makes her feelings clear but we don't really know what happens. It is very open but it does end on a hopeful note. But for a series with so many huge cliffhangers I wanted more closure. It was fitting and I enjoyed the ride all the way till the end. I still think this series is amazing with beautiful writing and an excellent concept. I knew the ending before I started reading so I was a bit prepared. Here is a video of Lauren Oliver talking about how she prefers us to finish the story ourselves. http://lauren-oliver.tumblr.com/post/... I'm not completely on board with that since I could finish the story myself even if everything that was open was tied up LOL but it's her book and still a great series. I cried during every one of them!

 "For a second I think about how easy it would be to pass back to the other side, to walk straight into the laboratories and offer myself up to the surgeons. 
 You were right; I was wrong. Get it out. 
 "My former people were not totally wrong. Love is a kind of possession. It's a poion. And if Alex no longer loves me, I can't bear to think that he might love somebody else." 
 "We don't have enough force to threaten them. I can't convince them if they won't listen. Welcome to the free world. We give people the power to choose. They can even choose the wrong thing. Beautiful, isn't it?
