Darkness Be My Friend (Tomorrow Series #4)

Ellie and her friends had been rescued. Airlifted out of their own country to the safe haven of New Zealand, they'd arrived burnt and injured and shocked, with broken bones, and scars inside and out. They did not want to go back. But five months later the war is not over, the nightmares continue, and there are two compelling reasons for them to return: a planned sabotage of the air base in Wirrawee and, most important, the families they left behind.
