At the end of The Eternity Cure we were left with a big cliffhanger. Now, Allie, Kanin, and Jackal are on their way to Eden on the heels of Sarren hoping to circumvent his intent to release a new plague on the world. After the huge loss of Zeke at the end of The Eternity Cure, Allie has given up, she's letting the demon out and becoming the monster she always wanted to avoid. There comes a point where everyone has to put aside the personal problems and focus on Sarren and the huge threat he poses to humanity. 
 As in the other two books in this series, I appreciate that Julie Kagawa doesn't write any "extra". There's no beating around the bush, she gets to the point and writes each scene as best as it should be. There are obvious moments that are driving the reader forward in the story. At the end of The Eternity Cure, Julie Kagawa decided to get the reader information that was kept from the main characters. I liked opening this book knowing something that the characters didn't and seeing everything unfold the way it did. 
 There are equally as many action and intense scenes as there are quiet moments. For me, the more contemplative times were what really made the book flow. I found the descriptions of the utter quiet and desolation of this post-apocalyptic at times both beautiful and scary. It hasn't gotten old even at the last book in the trilogy. 
 Julie Kagawa really put Allie and everyone through the ringer since book one and it's all lead up to this final showdown. Things are never easy but I liked that it never became too maudlin. The final fight is to ensure the hope for the future. I couldn't have asked for a better ending to the trilogy. There were some things I didn't want to see happen, but I never felt as though the storyline ever strayed from its natural path of where it was supposed to go. While part of me is sad that we're at the end, the other part is happy that it's over and the characters got their HEA.
