Ninja Nan

Jim's nan is completely ordinary. Or so Jim thinks. One day he finds a note on the fridge which changes everything... his nan has run away to be a ninja at the circus! 'Dear Jim, I am running away to join the circus. I know this will be a shock to you, but sometimes a Nan's just gotta do what a Nan's gotta do... Love, Your Nan (Ninja Nan!)'
