I actually thought this book was probably set in the past and was about some secret society before I picked it up as I had not read the blurb. But turns out it's a sci-fi novel and I wish I had picked this book up sooner!!!! Thank you Poonam for the recommendation. 
 There are so many things I liked about this book. 
 1. The interesting way in which the story is told. Since I had not read the blurb the narrative took me completely by surprise. I thought it was very unique and though it takes a little time to get used to I really liked the style. I think the plus point was that everyone's emotions were being interpreted from a transcript and not from a first person account. 
 2. The Phobos virus. I really loved how they described this. This could have so easily been neglected to being a zombie epidemic or people falling ill but I had chills reading this part. "Don't look at me" 
 3. Fast pace of the book This is a really fast read. I think it had do to do with the format of the book as well as the story line. 
 4. Last but not the least the A.I AIDAN. Wow!! This was so interesting it kept me guessing through out the book. So I know for a lot of people AIDAN probably had a male voice but to me it was a female entity. This is because I was reminded of another AI from the series "Person of Interest" that I totally loved as well. 
 Although this is a YA novel I liked how things although sappy in some parts did not take the focus away from the horror that Kady and Ezra were trying to survive. (view spoiler)[ Also the ending where Kady is talking to Ezra's mom came as a surprise. I knew she would figure somewhere in the evil corporation but did not think her entry would be like this (hide spoiler)] 
 This was a 4.5 star read for me.
