Fit not Fat...words that strike terror into Cassie's ample bosom. But she has no choice; she either loses her excess weight or her gall bladder. With the scalpel of Damocles hanging over her, she joins the gym for the first time in her life. Jane, the manager at the Fit not Fat Health Club, has her work cut out too. It's her job to win over the former staff, all of whom resent her appointment. It's a race against time for Jane to prove herself and for Cassie to lose those pounds. But is there a price to pay for the single-minded pursuit of fitness? And why are we all so obsessed with health?
