His arms flew to his side, a grunt of pain escaping his lungs. She grabbed for the knife as she scrambled away, but her fingers closed on air. No time. Her only chance was to put distance between them. Her fingers clawed at the dirt, her feet sliding across the trail, desperate for purchase. His hand closed on her ankle, and he snarled in fury. She kicked out as hard as she could, but his grip was too strong. Then she opened her mouth and let out a guttural, blood-curdling scream.

I screamed with her, wishing the whole city could hear my cries. I had already died at Ethan’s hands, and now the same thing was going to happen to my twin while I watched, helpless.

Ethan clapped his hand over Emma’s mouth, his pupils wide and dark. “I thought you were different,” he hissed. “But you’re just like your sister. Another lying bitch.”

Emma bit down on his hand, hard. The metallic taste of blood flooded her mouth. Ethan swore and pulled his hand away, and she screamed again.

“You’re a monster!” she shrieked, her voice ricocheting off the canyon walls. “You think I’d go anywhere with you after what you did to Sutton?”

He gave a wordless roar, his muscles tightening as he shoved her hard to the ground. This time he pulled a bandana out of his pocket, wadding it up and shoving it so far in her mouth she gagged. And then the knife was suddenly at her throat.

Emma stared up at him, tears coursing down her cheeks as he opened a thin, shallow cut on her neck. A white-hot fury coursed through me at the sight, so pure and strong I felt like I could rip straight through the veil between life and death.

And then, somehow, I was Emma. Or I was a part of her—not possessing her, exactly, but somehow joining my soul to hers for a moment, lending her the strength of my anger. With a sudden motion, her right leg broke free from below his, and we brought her knee to his groin with all of our combined might.

He groaned, his grip on her wrists slackening for just as long as it took her to roll out from under him. Then she was on her feet. She gasped for breath, and for one split second she thought she saw something impossible.

Her sister—shimmering and translucent in the moonlight—was next to her, standing fiercely over Ethan with her fists balled up. And then, just as quickly, she was gone.

Ethan was already on his feet again. His face was twisted beyond all recognition, a mask of hatred so utterly different from the boy she’d fallen in love with. She staggered away from him, pivoting on her heel to run—but lost her balance and sprawled forward.
