Cassie is a magical woman. Not in the tradition of Samantha or Sabrina. It is hard to say that anything that would be considered true magic ever occurs. Cassie does have a habit of appearing out of nowhere, of knowing who is there before she sees them, and of saying just the right thing to make a "coincidence" happen where it is needed. This was true in the movies as in the TV series.
The TV series starts out rather abruptly if you didn't see any or all of the movies. Brandon, Cassie's stepson, is being separated from his wife. Lori has a background of storytelling, if not outright reporting, that leads her back to the town newspaper.
Yes, Cassie is magical in the sense of being a wise and discerning woman who is both beautiful and loving. Cassie is the definition of optimistic. She wants to give everyone a chance, even long past where others would.
The TV series is a welcome addition to the Hallmark lineup after having been a fairly regular annual TV movie tradition.
