What if the Earth suddenly reversed its rotation-and time itself began to run backward? In the year 2211, humanity faces the most terrifying cosmic anomaly in history. The Sun no longer moves across the sky, oceans reverse their currents, weather patterns collapse, and global chaos spreads within hours. Scientists discover the cause: a mysterious, perfectly white celestial sphere-quickly named Snowball Planet-has entered Earth's orbit and is pulling the planet into a reverse-spin trajectory. To uncover the truth and stop the catastrophe, the Turkish Space Federation reactivates an old, legendary spacecraft: FLORYA. Leading the mission is Captain Merkür, a veteran born in space and known for his unmatched leadership. His small but elite crew includes: - Defne Yaz, a sharp meteorologist whose live broadcast first revealed the phenomenon- Altay, a fearless pilot capable of navigating extreme conditions- Kılıç, a survival expert trained for the harshest environments- Cenk, a brilliant electronics engineer with unmatched technical intuition As the FLORYA approaches Snowball Planet, the crew discovers something even more alarming than the reversed orbit: beneath the planet's ice shell lies a massive ocean of hyper-acidic liquid, hundreds of times more corrosive than sulfuric acid. A single rupture could trigger a wave of acid rain capable of destroying life across Earth. When a meteor storm cripples part of the ship and communications with Earth collapse, the crew must rely on their skills, loyalty, and sheer will to survive. With only 42 hours of oxygen left, they race against time to return home-while world governments argue over whether Snowball Planet should be destroyed or left intact. One choice saves Earth's rotation. The other risks apocalyptic fallout. REVERSE ORBIT is a gripping science fiction thriller combining deep-space exploration, high-stakes action, apocalyptic tension, and emotional character drama. Perfect for fans of dystopian sci-fi, planetary survival stories, and realistic space missions. A powerful, fast-paced novel about courage, sacrifice, and the fight to protect humanity when the rules of the universe suddenly break.
