Charm His Pants Off

A surprise ring at the doorbell on Valentine's Day confirms Amanda Clarke's suspicions. Her friend Sophie DuBois left someone behind when she came to Miss Zenobia Weekes' Charm School for Exceptional Young Ladies.
But the happy reunion grinds to a confusing halt when he asks about Sophie's quest to find her mother. And Amanda remembers she too came in search of answers about her own mother. Brianna Collins as well.
All of them forgetting their mothers the moment they showed up at the charm school? Someone, somehow, put a spell on them. But why?
Unless they find the witch who stole their memories, they may never know.
