Sara always gets lumbered with looking after her little brother Bernard, and summer project at the local school is no different. There's so much to do--football, judo, trampolining, model car making, computer games, and drama. But all Bernard wants to do is clothes design. Soon all the kids, led by Big Dan, are calling Bernard "Bernadette" and shoving him around. Sara wants to help but is worried she may make it worse. But "Bernadette" is a little boy with big ideas, and he has a plan up his very nicely designed sleeve.
