The Eternity Cure picks up with Allie journeying to find Kanin leaving her human companions behind in Eden. What Allie doesn't expect is that she will have to rely on those she can't completely trust and face her past. 
 I was very happy to learn at the end of The Immortal Rules that Kanin was still alive after Allie's abrupt departure from New Covington. Unfortunately he's not faring too well. Sarren has him, and is torturing him to the point of insanity. Allie knows that she must find him soon or it may be too late to save him. 
 Surprisingly enough, she comes to rely on her blood brother Jackal, the big bad guy in The Immortal Rules. His motives for wanting to help Allie are a bit shady considering there is no love lost between him and Kanin. I liked the addition of his character. He added some much needed humor and sarcasm to the book. I'm really interested to see where his loyalties will stand when all is said and done. He seems to have his own motives for Kanin's survival, but I don't think we've heard the whole truth about it. He's the character that no one wants around, yet seems to be forced to stay around anyway. I liked the interaction between him and Allie. 
 Events cause Allie to have to return to her human home New Covington. It was interesting to return for Allie to face her past and where she came from. I think it was important for her to be confronted with her human sideto understand the distinction between who she was in the past and who she is / will be in the future. Not only do we get Allie's past, but we get to learn more about the past in this world as well. A little more insight into the red lung virus and how it devastated the world. 
 Allie constantly struggles with the "monster" inside of her, but she does a good job of retaining her humanity despite others giving her grief for her decision to do so. I hope that, in light of events in this book, that this is not something that Allie will give away too quickly. It makes her unique and could truly cause people to look on vampires in a different light. 
 I appreciated the fact that Julie Kagawa knew when to elborate on certain scenes and when to skip ahead. Much of Allie's wandering through the desolate landscape could have drug the book down a lot and Kagawa seemed to understand this because, besides the beginning of the book, there's not much time where Allie is alone. This means, however, that every scene Kagawa chooses to write in detail is important. 
 I'll admit many things that ended up happening in this book I was prepared for. What took me by surprise was the way things ended up happening. I think this book, more than the Immortal Rules, leads right off into the next (and final?) book. I wish it was already released because I got to the end of The Eternity Cure and I was read to finish the story, but we now have to wait. I'm excited to find out how Kagawa will end the trilogy after having put our characters through so much, I hope they find happiness at the end.
