I was a bit worried about reading this book after having tried reading the novella about Brandt and not being able to finish it. I just couldn't get into it. While I had being curious about Brandt's ability it didn't suck me in like the rest of the series. Fortunately there was no need to be worried, cause as soon as I started I was immersed right away.This book was very reminiscent of Catching Fire/Mockingjay in a way. Can't really say too much cause I'll spoil it. It was just quite depressing. Depressing but still good nonetheless.Dez is now really showing signs of decline because of the Supremacy Drug, but even with her going loopy every so often she still holds it together. She has to fight to get Kale back, fight to save as many Supremacy kids before they are terminated and fight against the effects of the drug and her own survival. She has her despairing moments, but she soldiers on and keeps going. Nothing is going to keep her from getting Kale back, and I really admire that about Dez.The plot was it's usual fighting against time and Denazen to keep the rest of the Six's alive before Denazen can get their hands on them. Then we also have the new drug Domination which could save the Supremacy kids but also only has a 50% chance of survival. Then there is the cure for Supremacy that they have been trying to get their hands on and not quite succeeding. It all made for a very action-packed entertaining read, but it is still the same fighting that's been going on for the past 3 books really. Towards the end we do learn a very juicy new tidbit of information about Denazen that will turn everything on it's head, and I can't wait to find out what's going to happen to the rest of the Six's now.While technically speaking there was only a bit of plot development towards the end, and it was just a segue to the next book, it was still more than entertaining enough to keep me reading the whole way through. To fans of the Denazen series, this is a must read.
