The Jovian Astronautical-Biological Orbital Laboratory circles Jupiter and its moons. For seventeen year old Matt Bohles and his friends, "the Can" is home. Life on board the aging space station is cramped, apartan and dangerous. Its mission - to monitor incoming signals and transmissions in search of alien life - has so far proven fruitless. It is the only world Matt has ever known. Now Matt Bohles faces an impending crisis that threatens everything he knows and is. Unless he can prove himself as an invaluable member of the scientific team, he will be exiled to a filthy, perilous and unfamilar hell called Earth.
