For the millions who log in every day, Warcross isn't just a game--it's a way of life. The obsession started ten years ago and its fan base now spans the globe, some eager to escape from reality and others hoping to make a profit. Struggling to make ends meet, teenage hacker Emika Chen works as a bounty hunter, tracking down Warcross players who bet on the game illegally.

He needs a spy on the inside of this year's tournament in order to uncover a security problem . . . and he wants Emika for the job. With no time to lose, Emika's whisked off to Tokyo and thrust into a world of fame and fortune that she's only dreamed of. But soon her investigation uncovers a sinister plot, with major consequences for the entire Warcross empire.

In this sci-fi thriller, #1 New York Times bestselling author Marie Lu conjures an immersive, exhilarating world where choosing who to trust may be the biggest gamble of all.

Bounty hunters, hackers, and gamers, oh my! Warcross is an addictive page-turner with vivid action sequences and an endearing, snarky protagonist.

Warcross, a virtual reality game that almost everyone (if not everyone) plays. When Emika Chen accidentally glitches herself into the International Warcross Championships, she could never imagine that the game's creator would ask her to be a spy inside the Championships to uncover a sinister plo...

"What was once a hobby that many would look down upon, gaming has taken over the world by storm and many even build their careers off it. In the future, we can only expect it to grow exponentially and that is the future described in Warcross by Marie Lu. The story follows Emika Chen, a desperate young adult who is willing to lose everything for a bit of cash. The novel is set in the future where a virtual reality video game, Warcross, is loved by the public and is the biggest game on Earth. During the annual Warcross tournament, Emika decides to break into the games and steal a powerup worth enough to set her for life. The illegal act does not go according to her plan and soon enough reporters swarm her apartment.
This book was a fun read filled with vivid imagery and a large diverse character pool. However, other than that, the novel felt a bit too similar to others that I have read in the past. The plot twists were predictable and did not provide much of a shock. On top of that, the novel followed a stereotypical rags-to-riches story arc filled with diction that took me out of the story. There were also some parts where details seemed unnecessary and forced. Romance was another big aspect of the novel that did not fit in with the rest of the story, the descriptions were boring and irrelevant.

Overall, this novel is a decent science-fiction novel for those who want great detailed descriptions. I can see the appeal of this book but novels such as Ready Player One offer a better story that engaged me more." -Zhiyuan, Grade 9

I loved seeing an Asian woman as the lead. How rare it is to see a reflection of yourself in the main character in this role. I had to read this book twice to love it. The first time, I hated the ending, but the second time, years later, I was able to move on to the second book and have more closure. Although, I may not have loved all the plot lines, I did not put the book down, hoping for all the best for Emika's story.

So this book was good, right up until it counted.

It had its slow points, its parts that felt like you were crawling through mud on your stomach... In a downpour.

But that's only one of my qualms.

My biggest? Interchangeable characters. I HATE characters that act the same throughout the book. That respond the same way to things and all around have the same basic personality just with a few different kinks in them here and there.

That's what these characters were.

The entire concept was amazing, and most of the book was (characters interchangeability aside). I absolutely fell for Hideo, and yeah I guess I understand him falling for Emika.... But it happens all of a sudden there is no event that's like "up he's starting to fall in love with her" it's they meet, he sees her in a dress and BAM he wants her in all the ways.


I could have gotten past that if... IF the book didn't take a (poorly chosen) 180 at the end.

I mean, I was down to commit to the series when I knew Hideo was going to be there, but then he's made the bad guy and Lu tries to turn us on him (sorry hun, it didn't work for me. He's no dark one... But don't get me started on that)

All in all, I think there were a million different ways that things could have gone that would have been tremendously more entertaining than what was put out.

*Shrug* I'm sorry I'm not sorry

Warcross is another one of the well-written science fiction books written by Lu, and she masterfully uses foreshadowing to generate a constant tension across chapters and lead the reader on. Even with the constant hints that seem innocuous at first, the plot twists and turns in unexpected places and unexpected ways that fully utilize all of the backstory given in earlier passages. I think this book also has a good rhythm and flow, moving from one scene to another, sometimes diving into the details and other times moving forward quickly into the action.
As protagonist Emika Chen makes her way through a season of competitive gaming that she is suddenly thrown into, she is also entrusted to unravel a web of lies and deception that are embedded into the very code of the game she is playing. Attempting to solve a criminal kidnapping as part of her mission, she discovers the hidden intentions on both sides of the conflict and realizes that she has been manipulated into being a pawn for the warring forces taking over the physical and virtual world.
I would recommend this book for avid science fiction readers who are looking for a short yet striking series to start off.

Amazing, sci-fi classic. Very reminiscent of ready player one. The ending had me screaming but the second one had me crying by the end. Best book I've read in a long time!!

“Everything's science fiction until someone makes it science fact.”

Warcross—a game that has captured the world’s imagination, with a fantasied of millions, and a game that has sparked an international competition, and created a world within a world. Within this world, Emika Chen ekes out a living as an in-game bounty hunter, catching down those who participate in illegal activities online. A hunger for money lands her in the Warcross Championships, and before she knows it, Emika has skyrocketed to internet fame--and tangled herself in an in-game conspiracy with potentially deadly consequences.

Perfect for fans of “Ready Player One,” Marie Lu’s gaming-centric YA series is not one to be missed. With a mix of nonstop action, a team of lovable characters, political intrigue and sci-fi thrills, “Warcross” will have readers and non-readers alike guessing until the final page.

A fast-paced, imaginative scifi story. Make sure and have the sequel ready because you won't want to put this story down!

Well this was full of high action and tons of intrigue! Gotta love any character that has rainbow hair a full sleeve of tattoos, and is a kick butt hacker!!

Characters: 7/10
Plot: 9/10
Writing: 8/10
This definitely gave me Ready Player One vibes, which I really enjoyed. I loved the virtual environment of this world. The plot twist at the end was somewhat predictable--not intriguing enough to pull me into the sequel.
