Nowhere to run; one place left to hide. You're running from bullets through the streets of your own town. Your life's on the line and no-one's there to help.

What's happened?

When did safety turn to fear, peace turn to war, happiness turn to panic? When did your normal day become a nightmare?

Ellie and her friends struggle with the biggest questions life can offer in Darkness, Be My Friend, the fourth book in the award-winning Tomorrow series.
