Solarpunk Sabotage - Carrie Ray

In the year 2150, the city of Oasisa is a masterpiece of eco-engineering: crystal-clear air, vertical gardens, and zero waste. 14-year-old Elara and her tech-genius best friend discover that the "Infinite Battery" powering their green utopia isn't infinite at all-it's an ancient, leaking nuclear reactor buried directly beneath their school. If the reactor fails, the city dies. If they tell the adults, the panicked government will shut down the gardens and return to the "Dark Ages" of fossil fuels. Elara and a secret crew of young "Saboteurs" decide on a third option: they must break into the city's most restricted zones to replace the dying core with a truly renewable source, all while being hunted by "Peacekeepers" who think they are trying to destroy the world they are actually trying to save.
