Oh God. Please help me…’ In the darkness, Jo’s terrified voice sailed eerily on the breeze that rattled the tree branches above Allie’s head. Each word cut Allie like a blade. Panicked and desperate, she ran left, then right, then left again. But the voice never seemed to get any closer and it was getting harder to breathe. Her chest felt as if it was wrapped in bands of iron, inexorably tightening. Trying to summon the breath to speak, she panted harshly. ‘I can’t find you, Jo!’ she called weakly. ‘Where are you?’ ‘Allie!’ For some reason the hope in Jo’s voice broke her heart. ‘Help me! Please!’ A sob tore Allie’s throat as she ran. Trees that seemed to swoop down to snatch at her clothes with branches that ended in sharp points, like long, jagged nails. She ignored the pain. She had to find Jo. If she could just get to her in time, she’d live. She was exhausted by the time she saw Jo in the distance, lying on her back in a grove of trees, blonde hair glowing around her head like a halo.
