Taggie and Jemima are holidaying on their dad's farm. They know just what to expect - a tumbledown old cottage, sunshine and strawberry picking. But then Jemima sees a white squirrel wearing glasses...and soon after, their father is captured and whisked away to a faerie world that's fallen to Darkness. But why would anybody want to kidnap boring old Dad, especially the dreaded King of Night? Could it be that their family isn't quite as ordinary as they believed? As Taggie and Jemima venture into fantastic Realms, they discover magical powers they never knew they had. Powers they're going to need during the desperate race to save their father. But the sisters will also need all the friends they can find - no matter what kind of folk they are, or where in history they belong...
