Nana has come to look after her grandchildren, George and Becky. The day starts out as normal but, while trying to find extra special fruit for their home-made smoothies, Nana takes her grandchildren on an extraordinary adventure.

Starting with a trip to Mo’s greengrocers in Marlow, the children soon find themselves following Nana on a magical journey. Together, they encounter dangers, see wondrous sights and meet a very friendly but unusual shop keeper.

However, there is one little snag for George and Becky! Nana, who is particularly good at sewing, has made a crazy outfit that she insists on wearing. How embarrassing!

When they return from their adventure, the home-made smoothies taste extra delicious but there is an unexpected surprise for the children and Nana.
