Miranda investigates the mysterious disappearance of her big sister ten years ago.

Five-year-old Sara has a very special gift. She can fly. When her mother discovers this she promptly takes Sara to the hospital. The doctors poke, prod and probe as doctors invariably do, and it's no fun at all for young Sara. No one understands her. The thing is that she can only fly when she's so happy that it tingles in her tummy.
