5 full stars!!! I honestly wish I could give more because this book totally deserves it. :D 
 The plot of the book is as follows. We start of in the year 2575 where two mega corporations are at war over a small colony called Kerenza which mines a substance called Hermium. Suddenly, an invasion takes place when one of the corporations starts attacking the settlement. Kady and her ex-boyfriend Ezra find themselves scrambling to make their way to an evacuation vehicle. Before they know it, they are hurtling through space with an enemy warship on their tail. However, this is not their only problem, a deadly virus seems to be attacking personnel on board the ship while the AI that is supposed to protect them might be turning against them. As Kady hacks through the ship's systems, she stumbles across secrets and lies. Will she and Ezra make it out alive? 
 First, I thought the worldbuilding was phenomenal. The layout of this novel was so unique and creative. I can't even wrap my head around how schematics, IM messages and surveillance footage write ups created such a complex storyline and plot. It was definitely something new and refreshing. But everything was just solid. Yes, there is a fair bit of computer jargon and some defense terms, but that's what differentiates this book from others. I really commend the authors for taking time to research this stuff. It lent an air of authenticity to the book. 
 Second, the characters are FLAWLESS. Kady is spunky and so bad-ass. I love her hacking and computer witchery skills. While Ezra is so sweet and a very dependable kind of guy. There are total opposites but it really works for them. I loved their banter and interactions. Plus, they were so brave and their love for each other is so transcendent. Gosh! I was just rooting for them all the way. I also LOVED AIDAN. Yes, he is an evil AI computer. But, his personality was so layered. I mean his reasons for doing things at the end of the day could be forgiven. I can totally see why he did it. 
 Fourth, I loved the pacing. It was action all the way. The story flows seamlessly. There are twists and turns which will leave you reeling. Plus, I loved how the horror element was blended into the story. That was so EPIC. It just took the book to another level. I also loved how there is a mix of space espionage, mystery, murder, deception and a touch of romance. You get like bits of everything. So you are never really bored out of your mind. 
 Anyway, I loved this book. If you haven't read it. You should. Gosh! I need book two like right NOW!!! This one is going to my all time favourites shelf :D
