He's a father?! (Adoptive father figure Alastor and tiny tot reader/

Ash was born to a not so well off family. Said family wasn't the kindest to her, but when she is seven, they move to a large yet cheap house in New Orleans Louisiana. Ash Immediately falls in love with an old radio that her parents shove in the tiny room she was given. Her two older brothers, Jake and Keith, were given two of the larger rooms, her parents took the master, and used the other bedrooms as guest rooms, while shoving Ash in a small closet like room. However the room had a decently large space she could stand up in behind a small door that she had to crawl through. Her parents didn't care about the space and simply shoved some of the things left in the house there. One of them being an antic radio that, unknown to Ash, has been looking after her. What happens when a month after moving in, she finds out the radios secrets?
