“Who is he?” I screeched and flew at him, my claws tearing at his eyes. Smiling he flicked me away. I somersaulted through the air and came at him again.

“Look all around you, Kiera,” he smiled. “You’re trapped. You can’t possibly win.

I looked around to see a mass of black clouds racing through the sky towards us.

Clouds? I wondered. Do they have clouds in The Hollows?

Looking up again, I saw that they were changing, breaking apart, becoming smaller. But as my heart began to race in my chest, I could see that these weren’t harmless pieces of vapour. Each tiny piece had formed into the shape of a winged creature, a Vampyrus. Then, as if being punched in the face, the nightmare I’d had back in the Ragged Cove where I’d been fleeing along the shore hit me. In that nightmare, or as I now realised it to have been a vision, the clouds had broken up into pieces, thousands of pieces, each one taking on the form of a Vampyrus, just like they were now. Everything that I’d seen in my nightmares – visions – was now finally coming true. And in that instant, I could see running feet – they were booted. I was in a car and there were sirens wailing all around me. There were scratch marks, screaming – oh my god there was so much screaming. I was being swept up into the air. I was falling, I was being chased and the visions faded.

I looked down at the hard-packed ground and in the distance I could see shadows racing across the wasteland that we had crossed. But just like the approaching clouds, these weren’t really shadows. And as they raced forward, I could see their white faces, their red, burning eyes that gleamed like brake lights in a traffic jam. They were stripped to the waist and their chests looked bony and bent out of shape. A series of sharp, pointed ribs protruded through their pale, yellowy-white skin. These creatures were so sickly-looking, I thought they were ill in some way.

With my heart racing into my throat, I realised they looked strangely familiar. They looked like deformed copies of Kayla, Isidor, and me. They were the half-breeds Elias Munn had manufactured. Somehow, he had managed to produce them; not perfect copies, but grotesque imitations of us, like the reflections you see in those distorted mirrors at the fairground. That’s why the facility had been deserted and only a few left behind. He had known we were coming and had moved them. The disc! How had I been so blind? On the disc there had been drawings, diagrams of glass-like coffins – pods – there had to be another facility where these half-breeds had been kept. Like Hunt had been used as a decoy, Munn had led us to Ravenwood and the deserted facility so his army could be hidden and a cure for the virus could be found. But whatever he had used, the cure hadn’t been perfect.

The half-breeds’ skin looked oily, almost greasy, and I imagined that it would be slippery to touch. Their heads were long and narrow, with eyes fixed into the sides of their faces like birds. Their mouths were stretched open as if they were permanently screaming and they were crammed full of black, razor-sharp teeth. From the tops of their heads sprouted large, black, silky feathers, which they wore like Indian headdresses, and I wondered if this hadn’t been a side effect of the half-human and half-Vampyrus DNA not being decoded properly. Munn had created a tortured-looking race – mutants – that bore some tragic resemblance to Kayla, Isidor, and me.

“What have you done, you sick fucker!” I screamed and grabbed hold of Phillips.

“I think they look quite beautiful,” Phillips smiled, looking pleased with himself as he started to wrestle with me.

“What did you use?” I screeched at him. “The DNA that Hunt used was corrupted with a virus. What did you use?”

“Don’t you think we knew Hunt had deceived us? In your desperate attempt to leave the zoo, you cut your hands, remember?” he beamed. “You left some of that blood behind. We only needed a few drops, Kiera.”

“But they’re mutants! Freaks!” I roared at him in horror as we grappled with one another. “They’re nothing like me!”

“And that’s just how we want them,” Phillips leered. “Jesus, I couldn’t think of anything worse than an army of do-gooders like you, Kiera Hudson. We don’t want our army to be weak like you! What happened to you, Kiera? You were meant to be the chosen one, a great leader, a warrior who was going to lead us above ground and destroy the humans. But instead we were sent some bleeding heart, someone who loves humans. You might have been raised by humans, but you are not one of them!”

“And I’m not a Vampyrus either, Phillips!” I spat, trying to claw at his face, but he was too strong and knocked my hand away. “I’m a half-breed!”

“And like your friends, Kayla and Isidor, you will die a half-breed,” he barked. “You had it in your power, Kiera, to make your friends great, but instead you led them on this pointless journey. You could have made them true Vampyrus!”

“What, and end up like you?” I hissed, my face inches from his. “Bitter and twisted and full of hate? I’d rather they be dead, and so would I!”

Out of the corner of my eye, I saw Coanda sweep in beneath Phillips.

“Dead, you say?” Phillips laughed. “I can arrange that!” And then he was lunging for my face, his fangs spraying hot bile.

With one deadly swipe of his claw, Coanda separated Phillips’ his head from the rest of his body. Immediately, his head spun away, but it was as if for just a few fleeting seconds he was unaware of what had just happened to him. As his head flew away, Phillips’ mouth was opening and closing as if he were trying to say something to me.

“It’s a trap!” I roared at Coanda, pointing to the mass of Vampyrus that raced towards us through the sky, and the thousands of half-breeds that charged across the wasteland beneath us.

“I think you will find it is they who have been trapped,” Coanda grinned back at me with a wild look in his eyes. Then, without wasting another moment, he reached into one of the many pockets of his combat trousers and pulled out a small, brass horn. Raising it to his lips, he tilted his head back and blew into it. To my surprise, no sound came out.

Glancing down, I could just make out Potter as he clung weakly to a piece of rock jutting from the side of the Light House. As I watched, a Vampyrus swept in and knocked him from his perch.

“Potter!” I screamed, dropping like a stone through the air after him. I didn’t know if I would be able to catch him before he crashed into the burning lake below. The approaching Vampyrus raced towards me from both sides. Lowering my head and tucking my arms in beside me, I leant forward and raced towards him in a complete nosedive. My descent was so rapid that I could feel my flesh rippling against my skull. But I was catching up with him, and the world around me, the red rocks and the Light House, became a blur as if I had left time and space. With only inches to go before I was racing alongside Potter, another one of those giant Vampyrus swept in and clutched at me.

Pushing myself forward, my bones were rattling beneath my skin so much that I thought they were all going to snap. I inched towards Potter, but the Vampyrus wouldn’t give up and within moments, he was on me again. I reached out with my claws and thrust them between the Vampyrus’ ragged-looking ribs. A jet of black liquid spurted from the wound and the creature let out an agonising moan. I withdrew my claws and the Vampyrus slowed, leaving me the opportunity to grab hold of Potter and yank him free of the lava that bubbled and seethed just feet below us.

I put one arm tightly around him. He seemed dazed and disorientated.

“Are you okay?” I shouted at him.

Potter looked at me and to my complete surprise, he lent forward and kissed me on the cheek.

“Thank you, sweet-cheeks,” he smiled.

I looked at him numbly and with my free hand, I touched my cheek where he had kissed me.

“Why did you come back?” I whispered.

“I told you I was watching your back and you looked to be in trouble,” he said.

“Isidor is dead,” I told him.” He was murdered.

“By who?”

“You tell me?” I asked him, not taking my eyes from his, looking for any reaction.

“Is this like one of those pop quizzes?” he asked. “Because if it is, Kiera, I don’t know the answer. I didn’t kill him. Why would I?”

“Because he was just about to tell me who Elias Munn was,” I told him. “Apparently, Kayla got close to him just before she died.”

“That’s impossible,” Potter snapped, pulling away from me, so he could fly solo. “I was looking out for her. She was with me most of the time.”

“And that’s what scares me,” I told him.

But before Potter had a chance to say anything back, Coanda came racing towards us.

“Look, Kiera! Look!” Coanda was shouting.

I turned to see what appeared to be another giant wave of Vampyrus swoop down. But these were different, they weren’t attacking us, they were attacking the other Vampyrus. And unlike the others, these Vampyrus hadn’t taken on their natural form, they still looked human – well humans with wings – just like I did. They swept through the sky with the grace of eagles.

“Who are they?” I asked him.

“The resistance!” he laughed. “Damn! Have you ever seen such a beautiful sight!”

And they did look beautiful as they swept through the sky, their wings shimmering, muscles rippling as they attacked the Vampyrus. Within seconds, the sky above surrounding the Light House had become a battleground as Vampyrus fought with Vampyrus. Their fangs and claws sprayed blood as they tore and ripped at each other.

Then I saw him, Luke being chased by a flock of those black, bristling Vampyrus. They snatched and bit at him. He struggled with them, but he was outnumbered, and within moments he was spiralling out of the sky. A black shadow swooped in and snatched Luke away from the screaming half-breeds that waited below to tear him to pieces.

“What was that?” I asked breathlessly.
