The Stark Heir

In a world where Tony Stark has mastered technology, outwitted enemies, and survived the impossible, nothing prepares him for the one thing he never planned for: fatherhood.
When a mysterious package arrives at Stark Tower containing a baby girl with his DNA-and powers that eerily mirror his arc reactor-Tony is thrown into uncharted territory. With no memory of her origins and no explanation beyond a cryptic note, he's forced to confront a reality he can't engineer his way out of. As Pepper steps in to help stabilize the chaos and the Avengers inevitably get involved, the question becomes more than just where did she come from?-it's what is she?
Balancing sleepless nights, high-stakes investigations, and a child who can accidentally short-circuit a building, Tony must redefine what it means to protect something-not as Iron Man, but as a father. Because this time, it's not the world at risk.
It's his daughter.
