Grandma knows there’s only one way to rule the world. Let them eat cake.

Mother Merryweather is Sam Jones’s grandmother and a bit of a witch to boot (in a good way!). 

 When she wins a baking competition, her prize is a trip to Scotland to meet her TV chef hero. But there’s something waiting for her and Sam there. Something dark and devious and bearing a grudge.

This time, it’s going to take a lot more than a slice of Gran’s cake to sort out the Curse of Borage-Doone.
