The sequel novelization to the sequel television drama fo "A for Andromeda" is not as well constructed or believable as the first effort. Fred Hoyle and writing partner John Elliot begin "Andromeda Breakthrough" exactly where "A for Andromeda" ended. Rogue computer scientist John Fleming and Andromeda, the woman made in a lab on instructions from the supercomputer designed on another world, have destroyed the supercomputer and fled to a remote island off the coast of Scotland. Nearly all the main characters from "A for Andromeda" are back, except for British intelligence agent Judy Adamson, conspicuously absent, getting only a mention and not by name in the sequel, who was in the original arguably the central point of view for the story. Of course, since this is the sequel, the computer has to be rebuilt and we have to go through the questions again of what the intentions of its designers might be. "Andromeda Breakthrough" goes the route of political thriller, and the first half of the novel is hardly science fiction at all. Evil cartel Intel managed to get its hands on the secret design for the supercomputer and have sold it, under their supervision, to the struggling fictional Arab-oil country Azaran. With Intel's help, Azaran persuades or kidnaps the key scientists, including Fleming and Andromeda, to work on the computer and direct it to make Azaran a strong country in the world. There's murder, intrigue, and a couple of political coups d'etat. Hoyle and Elliot have demoted Kaufman to just a lackey for Intel, and substituted a new villain - French femme fatale Janine Gamboul, higher up in the Intel organization than Kaufman. The novel turns toward the science-fictional in the second half when a mistake that Fleming and fellow scientist on the project Madeline Dawnay had made in the days of the original novel becomes the cause of worldwide destruction.
As a sequel to "A for Andromeda" this story felt to me to be unnecessary. Issues that had been firmly established in the original are revisited from a "new" perspective that serves only to muddy up the messaging. The international intrigue portion is clumsy and superficial, and Gamboul is rather a cartoon villain. There are some intriguing ideas about how humanity has mishandled the environment and the potential causes of such mishandling, especially in the area of unintended consequences. Overall, though, this sequel lacks the tight plotting and concentrated thematics of the original.
