She rested her hand on the panel of the door to sense the level of power. Pulling her hand back, a ball of white shot from her palm and raced around the edges of both doors. She tugged one of the rings, and the door opened. I guess they weren't expecting high-powered company.

Inside, a passage glowed with the same sickly light we had seen above. A wrongness throbbed on the air that even Murdock could feel by the look on his face. He unholstered his gun, gave us a nod, and went in. Keeva rolled her eyes and pushed past him. "That gun isn't going to do much good here, big guy."

The far end of the corridor framed the parade ground in a simple arch. In the center, a naked, bone white figure stood, fairy wings undulating out from either side of him. Dark almond-shaped eyes stared from a worn face of ecstatic triumph. Seeing Gethin macLorcan in person made me realize that Shay's police sketch really had looked nothing like Corcan Sidhe. I had been seeing only the superficial similarities.

Shay lay crumpled on the ground just on the edge of the lawn. Ignoring him, Keeva walked onto the grass. Murdock trailed behind her with his gun drawn as I leaned down to check Shay. I couldn't tell if he was breathing. I wondered if he knew how over his head he had been. Pulling my dagger, I stepped up behind Keeva. The blade felt warm and alive in my hand, its runes grabbing the light around it.

Gethin had drawn himself inside another pentagram. Spirit jars sat at the five points, filled with herbs and water and the unmistakable shapes of hearts. Corcan lay at the center, his head near Gethin's feet. His body was rigid, and he stared straight up without seeing.

"You've done enough," said Keeva.

Gethin brought his gaze down, inspecting her with coal black eyes. His ears were not so much rounded as stunted points.

"I've just begun," he said. The voice. At once raspy and clear, like someone who had been smoking all night and talking too loud. It wasn't a voice to forget. Neither was his essence. Stinkwort and I had been so close the other night. We could have saved the last victim and even macDuin if we had been faster. His essence still felt wrong, but it had become muted, more fairy in nature, with a distasteful edge to it. As I moved closer, the hair on my arms bristled. He had already sealed the circle around the pentagram and erected a protection barrier. Most sane people did that with themselves on the outside.

"You don't have to do this. You got what you wanted," I said.

His eyes shifted to me. "What I wanted? No. What I wanted was to claim my mother's noble heritage. Instead, I must wear the disgusting wings of my traitorous father."

Keeva had circled around the pentagram. She kept one hand near her waist and flexed at the wrist. She was gauging the strength of the shield. When she reached the point opposite me, she shook her head. She hadn't found any weakness.

"You can't do this," Keeva said.

Gethin's face twisted into a sneer. "Only you think in terms of cannot." He spread his arms out. "Look at my power, de Danann. Look at your own. You waste yourself. If more of you had joined my mother's people, we would be ruling this place. Instead, you cower before the humans, content to take the dregs they offer."

"Let Corcan go. You don't need him anymore," I said.

"I need him to open the way. I am keeping my word to my mother, unlike my father. She found me a cure. Now we will cure the world." He began to chant. I recognized the spell. Good ol' Meryl had hit the nail on the head. Gethin was opening a door into chaos. Wind picked up in speed. Outside me fort, someone shot off a roman candle that glimmered red-orange through the hazy light of the protection barrier Gethin had erected. More explosions went off as the first display of fireworks appeared overhead.

"This spell will kill you!" I shouted. He faltered for a moment.

"You're wrong. It opens the door for The Defeated Who Will Conquer. They will ally with us, and we shall rule together." He had the fevered gleam in his eye of the rabidly insane. There wasn't going to be any reasoning with him.

He began chanting again. He raised a hand, and a burst of yellow light tore through the barrier and into the sky. It seemed to fly up forever and scatter among the clouds. A heavy silence spread around us except for Gethin's guttural muttering. Off in the distance, a moaning broke out. The ground vibrated with a deep thrumming. A torrent of air pounded down out of the sky, throwing us off our feet.

I lifted my head against the pressure. A towering wall of water ringed the walls of the fort, a dark, malevolent green surging toward the open sky all around and above us. Gethin had called up the sea. The wind died down. Confused shouting came from outside the walls, and more stray fireworks arced against the darkness.

Keeva flew to my side. "We can't penetrate the pentagram. The shield's stronger than anything I've seen."

"That's not the real problem." I looked up at the wall of water around us. "That's where all hell's going to break loose."

"Will someone please tell me what's going on?" said Murdock. He had not taken his eyes or his gun off Gethin.

I pointed at the seawall. "That is the gateway to a dimensional prison. The Dananns spellbound some critters called Fomorians. Gethin's breaching the barrier to let them out. They're big and nasty, and they're not going to be very happy to be here."

"Sorry I asked." He cocked his gun and aimed at Gethin. "So why don't I shoot him?"

"You can't see the barrier around the pentagram, but it will stop a bullet."

Gethin continued chanting, facing each of the points of the pentagram in turn. He picked up a stone blade and crawled around Corcan, inscribing runes into the ground. Pinpoints of light appeared in the spirit jars and raced around the hearts. They pulsed with an eldritch glow. Five columns of red light shot from them and pierced the clouds that capped the ring of water around the fort. A tremendous clap of thunder broke, the force of its vibration almost knocking us to the ground again. Above us, the clouds revolved in a circle like the beginning of a tornado. The center rippled and tore open, widening like the pupil of a dead eye. Oddly, no stars shone in the blanket of black. The surface of the wall of water rustled like a windblown curtain. Figures moved beneath the surface, huge unshapely things, vague and undefined.

"Keeva, use the binding spell to bind us all in here. We have to block Gethin's access to the water."

She closed her eyes in concentration. She shook her head. "I don't have your recall, Connor."

I fumbled in my pocket for Meryl's note and thrust it at her. "Learn quick. I'll try and distract him."

I flung myself at the pentagram. The invisible barrier yielded a few inches, then threw me off. Gethin didn't even notice. My dagger had gone flying when I landed on the ground. As I picked it up, the runes on the hilt glimmered. Bracing for the inevitable pain, I forced some of my own essence down my arm, and they burned brighter. The blade had some ability in it even if I couldn't access most of my own.

I approached the barrier again and slashed at it. A shower of sparks rent the air, pitting my skin with burns. Gethin did not stop chanting, but he glanced at me that time. I slashed again. More sparks cascaded over me, and I stumbled away. Gethin stretched out his arm, and a charge of energy hit me in the chest. I fell on my back.

I sat forward, clutching the hot, sore spot on my chest. It hurt like ten fists had pummeled me.

"Got it," said Keeva. She launched herself into the air above Gethin and began to chant. As she flew above us, a faint trail of blue light began to appear behind her. She had en the shorter spell by the sound of it. I could sense the weaving of her words bonding to the top of the battlements of the fort. The spell wouldn't take down the seawall, but if she managed to close Gethin inside the spell, his own spell would be trapped.
