Does this fic still exist?

This was one of the first fics I ever read. Pretty sure I read it on ff.net. It’s an OC from our world fic. A girl named Lily and her younger brother accidentally get transported to the wizarding world around Order of the Phoenix time. It happens via earthquake I think. Some OOTF members, I think Moody and Tonks, find them in the house. They take the siblings to headquarters and they are questioned. Lily explains as best she can. Turns out, she has magic. Her younger brother does not. I don’t remember much of the rest but I think she helps them fight Voldemort.
