Hailey Potter: The Last Safe House (harry potter x marvel)

Avengers Found Family. Maternal Natasha Romanoff.

Hailey Potter has never belonged-not in the cupboard under the stairs, not in Hogwarts, and certainly not in the home of an Avenger and the deadliest assassin.

The summer before her third year, she escapes the Dursleys-but she can't escape the scars they left behind. Sent to live with Natasha Romanoff, a woman she has never met, Hailey finds herself in an unfamiliar world of covert missions, redacted pasts, and...a loving family?

Natasha has spent her entire life being no one's family, being trained to cut every attachment at the throat. But now, with a niece she never knew she had, who is far too stubborn, far too broken, and unfortunately far too much like herself

How do you protect someone who has never been protected?

Spanning from the Prisoner of Azkaban to the Battle of Hogwarts & Endgame with PLENTY of Avengers fluff and twists.

(Detailed summaries by act/year available inside.)

*I suck at summaries but give it a try because it is a satisfying happy ending*
