Eleven-year-old Addison Carter has spent her entire life learning how to survive. After years of abuse from her biological parents and a nightmare foster placement, Addie has stopped believing that adults can be trusted. The only thing she has left is a phone number her friend secretly gives her-a lifeline for when everything becomes too much. But when Addie finally sends a desperate text, she accidentally messages the wrong number. Instead of her friend, a stranger named "Red" replies. What begins as a simple mistake turns into late-night conversations, bad jokes, and a growing group chat filled with people using strange codenames: Birb, Capsicle, Shellhead, Point Break, and more. Addie has no idea she's texting Earth's Mightiest Heroes. The Avengers don't know who Addie is at first, either. They only know that somewhere out there is a frightened little girl who asks questions no child should ever need answers to.

The Avengers were already having a terrible week when Amelia Hawke fell through their ceiling. Literally. Moments after Tony Stark creates Ultron and everything starts going catastrophically wrong, a portal opens in Avengers Tower and drops a sarcastic girl with impossible powers, suspiciously pretty braids, and absolutely no fear of gods, super soldiers, or billionaires. Amelia Hawke is chaotic, charming, and clearly hiding something. Thor trusts her immediately, which concerns everyone. Tony Stark wants to keep her. Natasha doesn't trust her. Bruce is having scientific breakdowns. And Steve Rogers? Steve is definitely not staring at her across briefing rooms. Probably.

Slowburn romance. Found family chaos. Cosmic secrets. Emotional damage disguised as banter. A deeply judgmental AI butler. And one super soldier discovering that the most dangerous thing in the room might actually be the girl smiling at him like she already knows him. ✨
