5 Stars!
Finally!! The development is here! Romy was so much better in this, and now I get why she was so soft in the first book. I loved her crazy sides, and I loved them fused too, though I definitely enjoyed the crazy side more. I like how she began to speak her mind more, but I wish she would have done it earlier, because the fact is, so many people were treating her like crap, but they were ALL using her or needed her in some way or another, including Atlas. I feel like all of these people who love or are supposed to care for her didn't do a good enough job in protecting her or her insanity when there were so many warning signs. They all cared about themselves or the cure, even after all she had been through, and now I know why Deimos made that comment about her head when she was fighting, and I'm glad there is an explanation for it now instead of them continuing on like there is nothing wrong.
All the side characters had a step up in this except some of her knot mates, which was a disappointment because I miss their humor, but I understand why it isn't the same. And even Tina I liked more, which I never thought I would say because I hated her in the first book, but as soon as she started supporting Romy's crazy side, I liked her more. I also liked Atlas a lot more too. I was iffy at him at times because I felt like he didn't care as much as he would say he did, especially with all Romy is going through, but I had to keep in mind he is very busy and she's not exactly telling him everything. I loved him the last half though when he really started showing his feelings and was finally vulnerable, because him keeping secrets from the person who can save them all was really getting on my nerves.
Overall, this was an amazing addition to the trilogy. It never dragged or was boring, or had unnecessary events. Everything that happened moved the plot, and I'm really excited to see what happens in the finale.
