What if you only had three minutes to save your life and the clock is already counting down? Three minutes: you wake up alone in a horrible land. A horn sounds. You realise you've been Called. Two minutes: they're getting closer and despite all your training you're exhausted, you can't see anywhere to hide. One minute: you're glad you can run. Nessa can't, her polio-twisted legs mean she'll never survive her Call, will she? Suddenly, a hand grabs your wrist and it's more painful than anything you have ever experienced before in your life...Time's up. Could you survive The Call?
