"Stop fighting!" a voice said at my ear.

I struggled harder, legs and arms flailing against the thing.

"Goddamn it, Paige. Don't fight! You're making it worse!"

Cortez? As my brain registered his voice, my body went still for a brief second. The light evaporated and I fell back, hitting the ground and gulping air. Cortez bent over me.

"They're koyut," he said. "They feed off energy. If you fight, you only produce more."

I pushed him away and sat up, wildly looking about for Savannah.

"She's right here," Cortez said, pointing at a prone form behind him. "She's fine. I'll carry her. We need to move past the trees."

He grabbed her up and we ran. When we reached the meadow beyond the trees, Cortez stopped me.

"We need to wake her," he said. "What did she cast?"

"I-I don't know."

I turned back toward the grove. Light trumpeted up from tree tops. The howls were muted, as if soundproofed within the grove. A man screamed.

"I need to help the others," I said, turning to run.

Cortez lunged and grabbed me. "Koyut don't kill. As soon as people lose consciousness, the koyut leave them alone. We need to concentrate on Savannah. What did she say?"

"It was Hebrew. I'm not good at Hebrew. I think-" I closed my eyes and willed my thumping heart to slow so I could concentrate. "She said something about summoning forces. Forces or energies, I'm not sure which."

"Summoning the energies of the earth. It's a sorcerer spell."

"You know it?"

"I know of it. I haven't learned it because it's not something I can ever imagine needing to use. It calls on the spirits of the earth, not to perform any particular task, but simply to respond and do as they wish. It's considered a chaos spell."

"No kidding," I said. "What was Savannah thinking?"

"It-it's never worked before," Savannah's thin voice said beside us. "All it ever does is make some noise and flashing lights. Like a prank. Dime-store magic. Only this time-"

"Only this time, it behaved precisely as intended," Cortez said. "Owing, no doubt, to your increasing strength. Plus the fact that you chose to cast it in a cemetery, a place rich in energy."

I knelt beside Savannah. "Are you okay?"

She pushed herself up onto her elbows. "Yeah. Sorry about that, guys." She gave a tiny smile. "Only it was kinda cool, wasn't it?"

We both glared at her.

"I mean, kinda cool in a bad way."

"I would suggest that is one spell you can safely remove from your repertoire," Cortez said. "I would also suggest that we return to the car before the lights attract-"

"I still need the dirt," I said.

"I'm fast," Savannah said. "I can get it."

"No!" we said in unison.

Cortez insisted on following me to the edge of the trees, so he could jump in if anything went wrong. It didn't. By now the lights had dimmed to a soft glow, illuminating the glade and the four figures lying blissfully unconscious within. I scooped dirt into both bags, shoved them into my pocket, and headed back to Cortez and Savannah.

"So that's what spirits look like?" Savannah asked, watching the swirling, multicolored glow.

"Not human spirits," I said. "Nature spirits and their energy. Let's go."

Savannah stepped away from the trees, then stopped and stared, transfixed.

"Yes, very pretty," I said, reaching for her arm. "Now move!"

Her body went rigid. A wave of physical energy shot from her, knocking both Cortez and me off our feet. The ground shivered. A low, nearly inaudible moan seemed to emanate from the earth itself. Geysers of dirt erupted, borne up on rocketing streams of light. Then the wind began to scream-not wail, but scream a high-pitched endless shriek that made me double over, hands clamped to my ears.

Cortez grabbed my shoulder and shook me, mouthing "To the car," once he had my attention. He hoisted Savannah's limp form over his shoulder and began to run. I followed.

As we crested the hill, I saw lights in the distance. Not the glow of spirits, but the very human illumination of flashlights and headlights. I looked at Cortez, but he had his head down, struggling to get Savannah to the top of the steep hill. I shouted for him, but the wail of the wind sucked the words from my mouth.

Lunging forward, I snagged the back of his shirt. He twisted, nearly tumbling onto me. I steadied him and gestured toward the road.

The flashing lights of police cars now cut through the night, joining a mob of flashlight beams spilling through the cemetery gates. Cortez's lips moved in a soundless curse and he wheeled around. I pointed at the woods to our left and he nodded.

As we raced for the woods, the shrieks and lights pursued us. No, that's a poor choice of words, implying the spirits were trying to attack us. They weren't. They simply followed, arising from the ground in our tracks. Elsewhere, the commotion seemed to be dying down. Or maybe it just seemed that way, in comparison to the chaos erupting around us. I wasn't about to stop for a scientific survey of the situation.

Once we reached the woods, Cortez lowered Savannah's body to the ground. Then he turned, raised his hands, and said a few words. As he swept his right hand across the air, the spirits vanished.

"I thought you couldn't do that kind of magic," I said, wheezing as I struggled for breath.
