She closed her eyes. That was it then. She had found herself a pair of magic glasses. They showed more than the eye could ever see. When Caroline discovers an old pair of spectacles in her father's junk shop she has no idea how important they are. Even when she puts them on and sees things very differently, she doesn't guess that the safety of another world depends on them.
In a race against time, Caroline has to tackle the ghastly Grimbles and keep her promise to return the spectacles to their rightful owner.
