The Final Atmosphere. The Atmosphere Series, #3

No exit. No air. No second chances. The true mastermind behind the "Atmosphere Habitats" project-a ruthless billionaire who sees human life as an experiment-emerges, threatening to "scrub" the air supply of the entire dome unless all political power is handed over. The city is plunged into chaos, the air is rationed, and time is running out. Evelyn and Leo are the only ones with enough expertise in the entire system to stop the villain.
They must hack the central "Atmosphere Core, " blending a tech thriller with extreme environmental high-stakes. In the high-tension finale, Evelyn and Leo must decide if they will stay and try to fix a broken world, or risk a daring escape through the airlocks and into the ruined Earth outside the dome, hoping for a future in a world without walls. Their love will be tested by the ultimate choice: a broken "perfect" life, or a free, dangerous life together in the open air.
