Climate Change with a Twist.
 England. Fifty years from now. As massive flooding caused by global warming creates chaos, there's another threat: millions of mobile wind turbines - 'turbs' as they're called - are disobeying instructions from their control computers. breaking the tethers connecting them to the power grid. howling with a piercing whine. vibrating with low frequency infrasound. slicing up birds, animals - and people. But why? What's the secret of the 'deviation factor'? Have the turb computers been hacked by terrorists? Can we destroy the turbs before the turbs destroy us - or will the turbs be turned into weapons for man to use against man? Time is running out for wind engineers Jack and Nessa to find the answers.
