Forged in Iron, Tempered in Steel (смешанная)

Tony Stark died to save the universe.
He expected silence, peace, maybe a chance to finally rest.
Instead, he wakes up choking on sand in a cave in Afghanistan, arc reactor burning in his chest and a future he already lived screaming in his skull. He’s alive again—too alive—and the universe has flipped the script: Tony Stark is now Toni Stark, same genius and sharper mouth, but in a new body and with a second chance she never asked for.
Armed with memories of alien invasions, genocidal robots, infinity stones, and an ending she refuses to repeat, Toni rebuilds her life from the ground up. She shuts down the weapons division early, creates world-saving tech years ahead of schedule, etc...
The world thinks she’s just a billionaire with good PR.
S.H.I.E.L.D. thinks she’s unpredictable.
The universe thinks she’s a variable.
Toni Stark is none of those things.
She’s a mother.
A genius.
A reformed disaster with a metal spine.
A woman forged in iron and tempered in steel.
And this time, she isn’t dying for the universe.
She’s going to make it live.
