“I’m not leaving you for that thing to eat while you’re still alive,” I whispered. “If it costs me my life, then so be it.”

“Stubborn until the end…” He sighed softly. “Stay until I’m dead then, but promise me when it’s over, you’ll find a way out. Promise me you’ll live.”

Feeling his panic and fear was hard enough, but seeing it written in hard lines across his face was even worse. His militant self-control was slipping, and I could see the true magnitude of his terror. And still he was thinking of me.

“No,” I said. “I won’t promise anything, because that would mean giving up. You won’t die, you won’t die.”

For a moment, Tristan’s fear turned to anger. “This wasn’t how it was supposed to go!”

“Then don’t let it end this way.” Never before had I felt such a pure sense of helplessness. Why couldn’t I have the power to help him, to make Tristan well again?

“Cécile!” He writhed in pain, his grip grinding the bones in my hand together. I closed my eyes and images of the sluag assaulted me. I would be powerless to stop it. It would sting me and then turn on Tristan. My mind recoiled at the thought of me lying there, paralyzed by venom, but still conscious enough to watch the monster strip the flesh from his face.

“No,” I whispered. “I won’t let it happen.” Pushing up his sleeve, I examined the cuts I had made. Not only had they not healed over with the preternatural speed at which trolls usually healed, they were bleeding profusely. I pressed my hand against them, trying to slow the flow, but crimson liquid seeped through my fingers and coated my hands.

Troll blood… blood magic.

Hands shaking, I tried to remember Anushka’s incantations, muttering the half-remembered phrases. But nothing happened.

“Please work!” Desperately, I called upon every ounce of will I had and used it to pull the foreign power filling the blood seeping from his veins. “Live, live, live,” I chanted. A wind rose, whistling through the tunnels. Every sound grew sharper and everything near me clearer to the eye. “Stop bleeding,” I shouted, and beneath my hands, I watched in amazement as Tristan’s wounds ceased to bleed and sealed over, leaving pale white scars in their place. My breath caught. “Tristan?”

His eyes remained closed. The seething pulse of his pain and delirium remained. The healed wounds were meaningless – I had done nothing to stop the progress of the venom. Desperately, I pulled power from all around me: from the rocks beneath my knees; the stagnant air in my lungs; and the water dripping down onto my face. I felt full, flush, but it was all for naught, because the power refused to acknowledge Tristan. He did not belong to this world.

A racking sob tore through me – for a moment, it had seemed I had all the power in the world at my fingertips. But I could not help him, so it meant nothing. I was powerless.
