Water is power. Truth is forbidden. And one forgotten district could change everything. Seventeen-year-old Mara Vey has spent her entire life inside Meridian, a tightly controlled city where every citizen's water is measured, every movement is watched, and the Directorate decides who receives more-and who receives less. Mara has also spent four years believing her older brother, Elias, died in a maintenance accident. Then she discovers something that should not exist: his missing identification tag, marked with three impossible words- Find District Thirteen. Officially, Meridian has only twelve districts. But as Mara follows the clues Elias left behind, she uncovers falsified death records, forbidden maps, secret tunnels, and a massive hidden water network operating beneath the city. Her search eventually leads beyond Meridian's walls to Veyra-a living community erased from history and built above one of the last great underground water reserves. The truth is worse than Mara imagined. For generations, Meridian has secretly depended on Veyra's water. Now the underground reservoir is beginning to fail, and both civilizations are running out of time. Elias wants to destroy the system that has stolen from Veyra for decades. The Directorate will do anything to preserve Meridian's control. Caught between them, Mara must decide whether exposing the truth can save both sides-or trigger the disaster everyone fears. The Last District: Where Water Is Power and Truth Is Forbidden is an original young adult dystopian thriller filled with mystery, survival, hidden history, family conflict, rebellion, political control, and the struggle for freedom in a world where a single resource determines who gets to survive. Perfect for readers who enjoy YA dystopian fiction, survival thrillers, futuristic societies, hidden-city mysteries, rebellion stories, climate fiction, and high-stakes adventures with strong female protagonists.
