Here to write an actual review on this book. 
 The world we live in is already so connected, just imagine if we could be connected more. That's what this book is. And it's not the "world is ending, Terminator style"; this shows us the good and the bad. Just like the internet we have now is. This story is everything Ready Player One should have been. Listen. 
 Emika Chen is our main character and a known bounty hunter at the start of this story. She hacks on the side, which helps her do 2 things: find her bounties easier, and glitch herself into the biggest game in the world. Warcross is an virtual reality game that everyone can play and Emika glitches herself into a worldwide tournament. Emika is sent off to Toyko to meet the creator and use her special skills to help him with his own special project, and here we have the set up of an amazing story that is more, but very much is, a video game story. 
 Every single character, from the main characters, to the characters we meet for 2 seconds, are fleshed out in such a way, it's like really meeting them. Emika is such a believable and lovable character, and she was easily relatable to me. 
 The story is built on virtual reality, family ties, and computer skills. The characters all have connections to all these things and they're the clear keys. 
 The world, virtual and real, were just so well built. There were questions, but you have to remember that there will be at least one more book and more room for world building and character development. 
 I've read that some found the twist at the end cheap, but I really never saw it. There were so many twist and turns, Marie Lu's storytelling is something out of a dream and I feel inclined to pick up the rest of her books.
