I think this movie has rekindled the magic from the earlier films. It's included the spooky Grey House which was absent in the last two films. A shame there's no sign of Isis the cat.
Grace is now a toddler and it's approaching Cassie's birthday that approaches Halloween. Things go wrong for her when her magical advice backfires, and she gets blamed. It turns out that the Grey Lady painting fell all on its own and a tear appeared on the painting. Cassie's ancestor was lonely but feared for her life as her birthday approached, which happened to be on the same date as Cassie's birthday and also the same time that the Grey Lady disappeared. Cassie's shop mysteriously catches fire, and grandpa is learning magic. His girlfriend's son is a magician who's fiance went off after he became financially broke. Martha's shop stinks because of a sewage leak next door but she used three cones instead of one that Cassie told her to use. Things all worked itself out but I can' help but wonder if Cassie is really the Grey Lady from 100 years ago.
Quite enjoyable and sparkly, if not slow in places.
