The DADA Teacher

Evangelina "Stripeless" Harrington broke up with Remus Lupin a long time ago.
Thirteen years, to be exact.
Now, she teaches at Hogwarts.
But, she made a mistake...
It wasn't his, nope, not at all.
It was hers.

Agnus "Aggie" Harrington grew up with lycanthropy because of Fenir Greyback.
She's lived in a werewolf colony since she was one.
She attends Hogwarts, and transforms in the shrieking shack every month, with Evie keeping her company.
They both need nobody but their family in their lives.

So what happens when the defense teacher turns out to be the person they're both running from?
The question they all ask: What then?
