Station Run

Vonni's life on Unity Station seems normal enough--school, gaming, watching the traders and starships come and go. No-one suspects she's hacked into the Virtual Reality learning program, Station Run, outpacing the game's slow, measured advancement to unlock and explore higher levels of virtual immersion on the space station. Then, in the virtual Unity Station, Vonni meets Dart, a scruffy boy who claims to live in a sector of the station that doesn't exist.
As she struggles to stay in the "game, " Vonni comes to realize that her programming skills have unearthed a closely-guarded secret--one that will rock the world of Unity Station and those who live there. As long as Vonni can get the word out before the administration tracks her down.
