Perry Stuart is a TV meteorologist who routinely works before the cameras. His life calm and ordered, his face familiar to every British household, Stuart's profound weather knowledge and accuracy have given him high status among forecasters, but no physical baptism by storm. Not, that is, until a fellow forecaster offers him a Caribbean hurricane-chasing ride in a small aeroplane. By frightening accident, Stuart discovers secrets from the ride, and back in England he faces threats and danger as deadly as anything that nature can evolve.
