Callista experiences an apparently paranormal event at the Okehampton Castle ruins and becomes a media sensation, when she successfully stops a gunman, but the effect on her life is dramatic.

Videos of the event appear on social media and go viral, and the intense media attention turns Callista's life into a nightmare. Her privacy is suddenly non-existent, and at the school where she teaches science, rumours spread like wildfire.

Cosmo, a geologist and the spokesman for a group of sceptics, publicly states as his opinion that extrasensory perception is a myth and that the event has been misrepresented or exaggerated.

But a TV chat show throws them together in a situation nobody could have foreseen, and they find they have to adjust their perceptions of each other.

How do two people, one calm and one seriously claustrophobic, who feel they are poles apart, cope for an hour and a half in total darkness in a stalled lift? And can they handle the consequences?
