This heartwarming and hilariously action-packed tale introduces Ben, a ten-year-old boy who is bored beyond belief every Friday night. Why? Because he has to stay at his Granny’s house. She is, quite simply, the most boring person on the planet: all she ever wants to do is play Scrabble, listen to classical music, and eat cabbage soup. Ben dreads these sleepovers, but one night, hidden under the lid of her biscuit tin, he discovers something incredible: diamonds! Suddenly, Ben learns two astonishing secrets about his seemingly dull grandmother. First, she was once an international jewel thief known as 'The Black Cat.' Second, she has one last, monumental job planned: to steal the ultimate prize, the Crown Jewels, and she needs Ben’s help to pull it off. Ben’s boring Granny has transformed into a Gangsta Granny, and together they hatch a daring, detailed plot to execute the heist of the century. This story is a celebration of the grandparent-grandchild bond, showing that you can never truly know the incredible lives and secrets people—especially grannies—might be hiding, and that extraordinary adventure can be found in the most unexpected places.
