For years, {y/n} was Tony Stark’s greatest, most fiercely guarded secret—kept safe from the villains, the paparazzi, and the crushing weight of the Stark legacy.

With a snap of his fingers, {y/n}’s future evaporated into dust. Five years passed in the blink of an eye for them, but for the rest of the universe, it was a grueling lifetime. When the Avengers brought everyone back, {y/n} returned to a world completely altered. Tony Stark had done the impossible—he saved the universe, and this time, everyone survived.

The world now knows exactly who he is as a father, because he raised a new child in the light: {y/n}’s little sister, Morgan. Now, thrust into the public eye not as Tony's protected heir, but as a ghost from his past, {y/n}’ must try to navigate high school and a world that aged five years without them, forced to share a home with a perfect, five-year-old sister who already has the life they were promised. Caught between loving their new family and battling a suffocating sense of jealousy, {y/n} has to figure out where they fit in a world that moved on without them.
