The Black Heart of the Station by Jay Allan Storey
Delinquent or Prophet? Whichever one teenager Josh Driscoll is, he may be the Station's only hope for survival.
The Station is a city buried deep beneath the surface of a frozen, lifeless earth, its origins lost in the mists of time. Josh's frequent rule-breaking exploits are focused on a single question - how did we get here?
But Josh goes too far when he steals a space-suit and escapes to the surface to explore.
As punishment, the governing Council, of which his father is a member,forcibly enrolls him as a novice monk at Saint Carmine's, the Station's resident monastery. At first desperate to escape, Josh finds himself drawn into the monastery's ancient texts.
Deciphering an encrypted journal hidden for centuries, Josh learns that the Black Heart, a computer complex sealed off after an ancient asteroid strike, may hold the answers he's been seeking, and may be all that can save the city from certain annihilation. When the deranged head of the Council is determined to demolish the Black Heart and doom them all, Josh leads a desperate battle to stop him.
But can Josh and his tiny band of followers prevail in time to avert catastrophe?
