Why do we need war and cancer and fights with our parents? What's wrong with sunscreen and holidays and trying to think positive? Get ready to see the world in a whole new light! Inspired by the success of her goal-setting and visualising efforts of last year, Natalie is determined to keep the Mastery Club going, but the challenges are stacking up: Nina has returned to her country life and home education, Clare is starting at a new school where she doesn't know anyone, Billy looks like he's about to give up on the Club to get serious about sport, and Sandy, as usual, is ready to argue with every one of Nina's crazy but beautiful ideas. Not only that but Natalie is being asked to take on her scariest challenge ever, someone she loves is sick, her own body is changing, her long-awaited overseas holiday isn't exactly as expected - and who is the dark stranger? Whether your goal is world peace, to win a mountain biking championship, or something as small as a mouse, The Hidden Order is full of different and very powerful approaches to a life philosophy that has so far been the domain of only the most enlightened masters... unless you're an 'Order Detective'... Are you ready to have your ideas turned upside down?
