It's 2299 and PSS 118 is just your typical school - except that it's a rickety old spaceship orbiting Jupiter. When the school is mysteriously attacked, Jack receives a cryptic message from his father (the school's recently-fired-for-tinkering-with-the-ship science teacher). Amidst the chaos, Jack discovers that his dad has built humanity's first light-speed engine and given Jack control of it. To save the ship, Jack catapults it hundreds of light-years away and right into the clutches of the first aliens humans have ever seen. School hasn't just gotten out, it's gone clear across the galaxy. And now it's up to Jack and his friends to get everyone home.
