"Almost never," Evanna said. "This is his private sanctuary. I've only been here a handful of times myself. The exceptions are those he pulls out of the Lake of Souls. He has to bring them here to turn them into Little People."

I stopped when she said that. I'd had a sudden premonition. "Evanna…" I began, but she shook her head.

"Ask no more questions," she said. "Desmond will explain the rest to you. It won't be long now."

Minutes later we reached what felt like the centre of the cave. There was a small pool of green liquid, a pile of blue robes and, standing beside them, Mr Tiny. He was staring at me sourly through the lenses of his thick glasses.

"Well, well," he drawled, hooking his thumbs behind his braces. "If it isn't the young martyr himself. Meet anyone interesting in the Lake of Souls?"

"Ignore him," Evanna said out of the side of her mouth.

Mr Tiny waddled forward and stopped a few metres shy of me. His eyes seemed to dance with fire this close up. "If I'd known what a nuisance you were going to be, I'd never have spawned you," he hissed.

"Too late now," I jeered.

"No it isn't," he said. "I could go back and erase you from the past, make it so you never lived. The universe would replace you. Somebody else would become the youngest ever Vampire Prince, hunt for the Vampaneze Lord, etc. – but you would never have existed. Your soul wouldn't just be destroyed – it would be unmade completely."

"Father," Evanna said warningly, "you know you aren't going to do that."

"But I could!" Mr Tiny insisted.

"Yes," she tutted, "but you won't. We have an agreement. I've upheld my end. Now it's your turn."

Mr Tiny muttered something unpleasant, then forced a fake smile. "Very well. I'm a man of my word. Let's get on with it. Darren, my woebegotten boy, get rid of that blanket and hop into the pool." He nodded at the green liquid.

"Why?" I asked stiffly.

"It's time to recast you."

A few minutes earlier, I wouldn't have known what he was talking about. But Evanna's hint had prepared me for this. "You want to turn me into a Little Person, don't you?" I said.

Mr Tiny's lips twitched. He glared at Evanna, but she shrugged innocently. "A right little know-it-all, aren't you?" he huffed, disgusted that I'd ruined his big surprise.

"How does it work?" I asked.

Mr Tiny crossed to the pool and crouched beside it. "This is the soup of creation," he said, running a finger through the thick green liquid. "It will become your blood, the fuel on which your new body runs. Your bones will be stripped bare when you step in. Your flesh, brain, organs and soul will dissolve. I shall mix the lot up and build a new body out of the mess." He grinned. "Those who've been through it tell me it's a most frightfully painful procedure, the worst they've ever known."

"What makes you think I'm going to do it?" I asked tightly. "I've seen how your Little People live, mindless, speechless, unable to remember their original identities, slaves to your whims, eating the flesh of dead animals – even humans! Why should I place myself under your spell like that?"

"No deal with my daughter if you don't," Mr Tiny said simply.

I shook my head stubbornly. I knew Evanna was trying to out-fox Mr Tiny, but I didn't see why this was necessary. How could I help bring about peace between the vampires and vampaneze by going through a load of pain and becoming a Little Person? It didn't make sense.

As if reading my thoughts, Evanna said softly, "This is for you, Darren. It has nothing to do with what is happening in the present, or the War of the Scars. This is your only hope of escaping the pull of the Lake of Souls and going to Paradise. You can live a full life as you are, in this waste world, and return to the Lake when you die. Or you can trust us and place yourself in our fathers hands."

"I trust you," I said to Evanna, shooting an arch look at Mr Tiny.

"Oh, my boy, if you only knew how much that hurts," Mr Tiny said miserably, then laughed. "Enough of the dawdling. You either do this or you don't. But take heed, daughter – by making the offer, I've fulfilled my end of the bargain. If the boy refuses to accept your advice, on his head be it. I'll expect you to keep your word."

Evanna looked at me questioningly, not placing any pressure on me. I thought about it at length. I hated the idea of becoming a Little Person. It wasn't so much the pain as letting Mr Tiny become my master. And what if Evanna was lying? I'd said I trusted the witch, but thinking back, I realized there was precious little reason to trust her. She'd never betrayed her father before, or worked for the good of any individual. Why start now? What if this was a twisted scheme to ensnare me, and she was in league with Mr Tiny, or had been tricked into doing his bidding? The whole thing stank of a trap.

But what other option had I? Give Evanna the cold shoulder, refuse to enter the pool, walk away? Even assuming Mr Tiny let me leave, and the monsters in the tunnel didn't catch me, what would I have to look forward to? A life lived in a world full of dragons, followed by eternity in the Lake of Souls, wasn't my idea of a good time! In the end I decided it was better to gamble and hope for the best.

"OK," I said reluctantly. "But there's one condition."

"You're in no position to set conditions," Mr Tiny growled.

"Maybe not," I agreed, "but I'm setting one anyway. I'll only do it if you guarantee me a free memory. I don't want to wind up like Harkat, not knowing who I was, obeying your orders because I've no free will of my own. I'm not sure what you have planned for me once I become a Little Person, but if it involves serving as one of your fog-brained slaves…"

"It doesn't," Mr Tiny interrupted. "I admit I quite like the idea of having you toady to me for a few million years or so, but my daughter was very precise when it came to the terms of our agreement. You won't be able to talk but that's the only restriction."

"Why won't I be able to talk?" I frowned.

"Because I'm sick of listening to you!" Mr Tiny barked. "Besides, you won't need to speak. Most of my Little People don't. Muteness hasn't harmed any of the others, and it won't harm you."

"OK," I muttered. I didn't like it, but I could see there was no point arguing. Stepping up to the edge of the pool, I shrugged off the blanket which the Little People had draped around me shortly after I emerged from the Lake of Souls. I stared into the dark green liquid. I couldn't see my reflection in it. "What-" I started to ask.

"No time for questions!" Mr Tiny barked and nudged me hard with an elbow. I teetered on the edge of the pool a moment, arms flailing, then splashed heavily into what felt like the sizzling fires of hell.

Instant agony and burning. My flesh bubbled, then boiled away. I tried to scream but my lips and tongue had already come undone. My eyes and ears melted. No sensation except pain.

The liquid stripped my flesh from my bones, then set to work on the marrow within the bones. Next it burnt through to my inner organs, then ate me up from the inside out. Inside my head my brain sizzled like a knob of butter in a heated frying pan, and melted down just as quickly. My left arm – just bone now – tore loose from my body and floated away. It was soon followed by my lower right leg. Then I came apart completely, limbs, charred organs, tiny strips of flesh, bare pieces of bone. All that stayed constant was the pain, which hadn't lessened in the slightest.

In the midst of my suffering came a moment of spiritual calm. With whatever remained of my brain, I became aware of a separation. There was another presence in the pool with me. At first I was confused, but then I realized it was the flicker of Sam Grest's soul which I'd carried within me since drinking his blood at the time of his death. Sam had passed on to Paradise many years ago, and now this final shard of his spirit was departing this world too. In my mind's eye a face formed in the liquid, young and carefree, smiling in spite of the torment, popping a pickled onion into his mouth. Sam winked at me. A ghostly hand saluted. Then he was gone and I was finally, totally alone.
