help me please! :)

i forgot the name and half the story, but basically mc had a bad family so she went to live with some of the powerful people in the country and the woman she went to was really tall and was the duke? i think, she also had a son or two they were also tall. giants. After they tried adopting her, the family (ofc) intervened and took them to court where they tried to get her back from the powerful family but they failed. that’s all i read. this was ages ago too so i don’t really know or remember it’s name.
