"Halloweentown" Series
Marnie gets stuck in Halloweentown with her grandmother for a year. And, as much as she loves her grandmother, she misses her mother and her siblings. She tries to focus on her magic training, but her homesickness begins to consume her.
As Marnie becomes more and more depressed, Aggie becomes increasingly alarmed for her granddaughter's physical and mental health. Will she find a way to open the portal and return Marnie to the Mortal Realm? Or can she find ways to help Marnie cope until next Halloween, when the portal will open on its own, and Marnie can return home?
