2.5 stars. 
 "Perhaps bravery is simply the face humanity wraps around its collective madness." 
 Well, I have mixed feelings with this book. It has a great premise, I like the main characters but I was expecting something more. Even though it's a big book you read it really fast but it just didn't blown my mind. 
 I didn't like some things: The format of the book is legitimately original but in some pages I struggled to keep reading them, especially the chats between Ezra and Kady and other characters. They text with words like "chum" which I suppose it's kinda an slang but it made me cringe lol. Also I felt some dull chapters about data information about the space ships. Too much information for my brain ahh. And about the virus I was expecting something more scary idk. I can't even remember why the conflict with BeiTech. I read this a few months ago. 
 The characters are cool, Ezra and Kady relationship is something different from other books I've read, they're a silly cute relationship haha. 
 "You have me. Until ever last star in the galaxy dies." 
 But my favorite one is Mcnulty. AIDEN or whatever what's his name it's creepy as hell. I don't like that thing. 
 The ending I thought it was a okay, BUT the revelation about the Illuminae group holy cow WHAT THE ACTUAL F*CK. But I'm just not amazed with this book as everyone is. I can understand the hype though. 
 I'm still hesitating to read Gemina but we'll see :)
