Something strange and terrible was happening to Earth...
The city seemed to explode right before Conway's eyes. First the flash of blinding light, then the thundering crash. Everywhere around him was destruction and death. It was the same in all the other major cities of the world. Conway knew that it was somehow connected with that last fateful expedition... and the creature they had unknowingly brought back - which was now occupying the body of his wife!
Geoffrey Hoyle (born 1942) is an English science fiction writer, best known for the works which he co-authored with his father, the astronomer Fred Hoyle. About half of Fred Hoyle's science fiction works were co-authored with his son.
He was educated at Bryanston School in Dorset, and then entered Cambridge where he read fine arts. After 1964, Hoyle worked in London in the field of modern communications and the film/television industry. Unlike his father, he is not a scientist, and contributed to the more "human" side of their co-authored novels – however, he did work as a "scientific advisor" to some series such as Timeslip.
