Night Speakers

Night after night Elena Matt and Tima wake at exactly the same time with no idea why. It's messing up their lives - so they venture out into the dark and find each other. That's when they realise their astounding power they can communicate with animals. Something is happening over on the industrial estate something which is emitting sounds that only they can hear and it's killing any winged thing that crosses its path. There's nobody to fight it but themselves!
