Cyfrinach Nana Crwca is the Welsh Edition of Gangsta Granny by popular childrens author David Walliams. This marvellous adaptation is a great addition to our Welsh language books.

Our hero Ben is bored beyond belief after he is made to stay at his grandma’s house. She’s the boringest grandma ever: all she wants to do is to play Scrabble, and eat cabbage soup. But Ben doesn’t know that his grandma was once an international jewel thief.
