  Summary

  Morgan Stark wanted an older sister. Tony Stark gave her three traumatized, superpowered young adults instead.
  Now he’s parenting:
  * Peter Parker, 19, Spider-Man with too much guilt.
  * Harley Keener, 21, genius with a rage problem and a potato gun.
  * Reyna Voss-Reid, 16, a super-soldier from 1929 just thawed out of cryostasis.
  Tony didn’t plan to build a new family—but somehow, between the trauma, chaos, and midnight snack raids, that’s exactly what happened.
