PREDICTIVE - suspense book, work in progress

 A family find themselves trapped in the town of Predictive, towned with Tredmill. Here no speaking or noise is allowed. The teenagers' mobiles are swapped for Preds the latest communication device which does not make calls and can only be used for texting by writing with your finger across the screen, and for listening to music that no one else can hear.

There are no adults to supervise or nag as anyone over twenty one mysteriously disappears. The younger people spend their time in the games and music rooms, or take away restaurants where food is fed continuously for free.

And, no one questions it because the consequences are dire.

Who has imprisoned them and where are the adults?
