Public Summary Everyone knows Tony Stark’s daughter. Nobody knows what she’s capable of. Y/N Stark is the heiress to Stark Industries, holder of Legacy Gold-Level Clearance, and secretly one of the most powerful beings on Earth. The Avengers think she’s just Tony’s spoiled genius daughter. Tony thinks he knows everything about his kid. They’re both very, very wrong. Because the most dangerous thing in Stark Tower isn’t an Avenger. It’s the girl they’ve all been underestimating.
