As you take a step, a crack slithers up the glass floor, forcing you to hesitate to step again. You realize, however, it's not the floor that's made of glass... it's you. A porcelain doll made to run isn't supposed to be possible, but she was created by the Professor against all odds. This doll, destined to leap into life, has her freedom threatened by those lost on dusty shelves. How could a doll as delicate as she, be able to run on glass feet? She must determine how much she is willing to give to reach this potential, but she first needs to decide... is she willing to take a jump into the dark when a fall could shatter her?
