Warcross follows teenage hacker Emika Chen, who lives in New York City. A bounty hunter, Emika rides her way through the grand city in order to collect money so she can pay up her deceased father's gambling debts. The world in which Lu creates has a fascinating virtual reality system, created by Hideo Tanaka, called the NeuroLink. Within the Link is the game Warcross, as the title dictates, which is a tournament conducted by players across the globe. When Emika accidentally works her way into the Warcross opening ceremony, Hideo Tanaka offers her a job: to take down the hunter who is hacking through the NeuroLink. 
 This book was stunning. I loved the writing, the characters, the plot, the pacing and the world that Marie Lu has created. In an interview or something like that, it was said that this book is a mixture of all the things she loves. If she keeps going like this, her books are going to become even more successful than they are. This was an astounding, thrilling, heart-pounding ride and I loved every second of it. 
 The characters were so vividly created that I could see them in my head running around the Warcross tournaments and playing the game. I could see Hideo and Hammie and Emika and everyone. Gosh, I loved the NeuroLink as well. Sign me up for that! I could also definitely see how the world was affected by the NeuroLink and how this connects to how we are affected by the internet itself. 
 The pop culture references in this book were just amazing. I loved Emika's interest in Harry Potter and how it was mentioned in the novel. I loved seeing her memories of her childhood interests, it was all just so tantalizing! The storyline in the book did not fall downhill for me at all, I enjoyed every moment of this experience. The ending led into the potentials for an amazing sequel and conclusion to this fantastic duology. I can already see how this is going to go down. 
 Also, even though I guessed who Zero was, I was still stunned that Marie Lu decided to take that turn of events! It was so good to see how (view spoiler)[Sasuke (hide spoiler)] had kinda planned all of this. I dunno, I just loved it. 
 Such a good book. Can't wait for the second one.
