I got this title from NetGalley for a honest review.This review contains spoilers.What to say about this book? It wasn’t totally boring, it had its good parts, but the middle dragged. It happens with me sometimes in bridge books, where the story stalls, and I get bored. I have a bad habit when this happens of wandering off to read something bright, shiny, and new. I am fickle like that.So here is the story, I was thoroughly, and emotionally involved until about forty percent. I really liked the Gabriel arc, meeting new immunes, and seeing the depths of horror a mad man will go. The story build up to this point was exciting, and raw, with wild immunes, Skylar cut off from the camp, and Tania still shook up from the choices she had to make, and the death of her lifelong friend and mentor. Then Tania and Skylar have a spat, and things just slow down to a crawl. The story then focuses more on Darwin, and what Russell’s (may he be punted out a air lock) choices have done to the power structure surrounding the Elevator. In putting Grillo in charge of Darwin, Russell gave the Jacobites a foothold to power. Also I want to add I am not really feeling the love triangle that is going on in this book. The fight between Skyler and Tania feels juvenile, and the relationship between Skyler and Ana just isn’t.I don’t think Ana is long for this world, just saying. So, I didn’t really snap back into the book until close to the ending where the author gifts us with a HUGE cliffhanger.
