Then Gwendolyn Cate arrives – Mimi’s solution to all their problems. Gwen is a ballet dancer in training from Toronto, come to shine things up a bit. But Reenie’s memory of the fairy-like girl turns out to be just that: a memory. At first, Gwen seems like another person entirely, keeping secrets and not letting Reenie in. Gwen is friendly, but not as friendly as Reenie wants her to be. She wants a best friend, not an older sister. So Reenie decides to take matters into her own hands and figures out a way to simultaneously draw out Gwen’s secrets, make everyone happy, and save Sandy Shores. Only things don’t quite go as planned.
