Sara and Marcus hide in forests and abandoned houses, fighting to survive extreme weather events and the violent gangs that hunt for people and resources. Both are parents but only Sara has hope that her children are still alive.

When she realises she needs Marcus’ help to find her family, their journey becomes fraught with complication. A brief encounter with a pregnant woman changes everything as she grapples with the complex nature of risk and the reliability of her own instincts.

As she moves through the shadows, Sara discovers that fear can deliver freedom, love transcends loss and to kill means to live another day.
