In the Underground Safe Haven, your future is not chosen — it is calculated. At the age of fifteen, every citizen is fed into the Specializator: a machine that injects a serum into your blood, reads your brain, and decides who you will be for the rest of your life. Blue crystal for guards. White for scientists. Purple for teachers. Red for artists. The system has worked flawlessly for 256 years. Until it meets Mars Sury. Born the last naturally conceived human in a society that has outlawed natural birth, Mars has always been an exception. Curious, rebellious, and impossible to categorize, he grows up in a world of strict rules he was never quite built to follow. When he accidentally uncovers a secret that threatens the foundation of the entire system — a flaw the Council will do anything to suppress — Mars finds himself in the middle of something far larger than he ever intended. And then there is Sola D'Aron. Brilliant, fierce, and born on the wrong side of the crystal divide, she is everything the machine should have predicted — and everything the Council would rather erase. What begins as a mission to protect her becomes something neither of them expected. The Last Natural is a story about a world that decides who you are before you can choose yourself — and one boy who refuses to let it.
