A Crack in the Sky (Greenhouse Chronicles) Mark Peter Hughes Reprint edition

Thirteen-year-old Eli Papadapoulous is worried. Even though he's part of in the most powerful family in the world. Even though his grandfather founded InfiniCorp, the massive corporation that runs everything in the bustling dome-cities. Even though InfiniCorp ads and billboards are plastered everywhere, proclaiming:
DON'T WORRY! INFINICORP IS TAKING CARE OF EVERYTHING!
Recently, Eli noticed there's something wrong with the artificial sky. It keeps shorting out, displaying strange colors and random, pixellated images. And though the Department of Cool and Comfortable Air is working overtime, the dome-city is hotter than it's ever been.
Eli has been raised to believe that the dome-cities are safe and comfortable; that the important thing is to keep working, keep consuming; that InfiniCorp knows better than he, and he should leave everything in their hands.
But now he begins asking questions.
