Children of Steel was the ninth Sarah Jane Adventures audiobook release. It was written by Martin Day, produced for AudioGO and read by Daniel Anthony. It accompanied the CBBC broadcast of series 5, and was one of only two releases in the range read by someone other than Elisabeth Sladen, as the actress had died earlier that year.
A steam-powered robot causes chaos for Sarah and friends, in this exclusive audio story read by Daniel Anthony.
Sarah speculates that the probe was used as the 'brain' that powered the 'Difference Golem'; a mechanical servant built by eccentric inventor Sir Joseph Montague. She suggests destroying it, to prevent such advanced technology from falling into the wrong hands, but Rani persuades her that this would be wrong, as the golem could have been sentient. So she, Rani, Sky and Clyde travel to Holcote House, the former residence of Sir Joseph, in search of its body. But they are soon to discover that meddling with artificial intelligence can have dangerous consequences...
Sarah wants to buy the head, but also another woman is interested in it. When the bidding is over 130 pounds the woman soundenly stopps bidding and Sarah gets the head for 140 pounds.
Since Sarah only got the head of Adam she tries to find his body. Mr Smith tells her that the head was sold by Oliver Guide who lives at Holcote House. The Bannerman Road gang decides to look there for the body. Oliver Guide shows them his cellar.
Since the metal body is difficult to find Sky uses her electric power to find it. After body and head are put together Sky activats Adam with her electric power. Adam becomes alive. He tells them that when he was deactivated part of him was still aware of the passing months and years and part of him still existed in the darkness. He felt lonely.
Sarah asks Adam to come with them when suddenly the woman from the auction appears in the cellar. She attacks Adam and soon both are gone.
Sarah and her friends finally find Adam in a fabric. Adam has already activated may other Difference Golems and is going to activate more. Adam lets them come to live by putting parts of his mind into the robots, whom he calls his children. He soon realises that each time he gives them the spark of life he is diminished by the process. Sometimes he even seems to forget who he is. Rani convinces Adam that he can't keep up dividing a brain like that. Adam is pleased that Rani calls him a "him" instead of an "it". He listens to her, takes the research probe out of his brain and gives it to his daughter who promises to bring the probe back to the future. After this Adam's mechanical body is just as lifeless as his children. However he lives on and manages to get the daughter that later travels back in time to bring him or the probe back to the future.
