Teenager Bram Argent comes home from school one day to find his parents are gone. He knows what this means: his mother, a brilliant AI scientist, has done something that has gone out of control. She needs three weeks to put it right. The family has an agreed plan for what Bram should do if this happens.
With a schoolfriend, Stella, and a wisecracking AI toy duck called Bob, he is now on the run, at least till his parents have done what needs doing to stop the crazed virtual being Ahriman...
Who has seen the Dr Who episode Terror Of The Autons? In the 1970s, when it was made, there was a common product that was simply everywhere - plastic. Anything from a garden hose to a plastic daffodil could attack you and a comfy chair could get too comfortable and swallow you!
Have a guess what the "simply-everywhere" product is now? Right! The Internet. Wifi. Everything is linked up. Even a pool cleaner can be connected. Some time ago I read of a fridge that would let you know when it needed restocking.
Now imagine that pool cleaning hose or fridge being sent after you. A kettle. A coffee machine. A photocopier - anything with links to the WWW - spitting out boiling hot metal. Scary, isn't it?
It's what happens to Bram and Stella. They need to stay alive and running long enough for Mrs Argent to produce something to destroy Ahriman, her own creation. If caught, they will be hostages at best, slaughtered at worst, on the orders of a creature that has become self-aware and wants to take over the world. And its "junkbots" are becoming more and more smooth and properly built.
The book is great fun, with nonstop action and humour. It's not The Laws Of Magic, but it isn't meant to be. Despite the age of the main characters - fourteen - it's really a middle-grade book, quite accessible and readable to primary school children, who will enjoy it.
