Squib adopts harry fic

[DanniiGirl]

I can't remember where I read it, possibly on Roughtrade, maybe on Ao3.

A squib woman adopts Harry and wants to open a restaurant but the only place she can get is in Knockturn alley and she ends up with loads of businesses in the end completely transforming the look of the place. I remember that Lucius Malfoy helps her with some sort of legislation change in return for getting a permanent table at the restaurant.
