From #1 New York Times bestselling author Marie Lu--when a game called Warcross takes the world by storm, one girl hacks her way into its dangerous depths.
 
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. But the bounty-hunting world is a competitive one, and survival has not been easy. To make some quick cash, Emika takes a risk and hacks into the opening game of the international Warcross Championships--only to accidentally glitch herself into the action and become an overnight sensation.
Convinced she's going to be arrested, Emika is shocked when instead she gets a call from the game's creator, the elusive young billionaire Hideo Tanaka, with an irresistible offer. 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.
