At the end of the block, the Common glowed with more radiant essence. The light burned brightest through the bare limbs of the trees where the land sloped up to the towering Civil War monument and the fairy hill beyond it. Fairies of all kinds filled the sky, their wings flaming with essence as they swooped and swirled in dance. As we ran down the lane that passed the bandstand, the crowd swelled, slowing down as more people flooded into the park. Everyone wanted to be on the hill.

I stopped, amazed. An inverted funnel of misty gray light twisted into the sky, long wisps of the Taint revolving around it.

Dylan spoke in my ear with awe and wonder in his voice. “It’s really opening, Connor. The veil is opening.”

I pushed ahead. “That thing better be exit only.”

Thousands of laughing and shouting people packed the blocked-off streets around the Common. Groups gathered and merged with a confusion of harps and lutes, drums, horns, and electric guitars on portable amps. Anything that could make a noise, someone banged, blew, or strummed-elven death dirges clashing with Irish bands playing tympani punk, dwarven horns blasting against Gaelic windpipes against police whistles and megaphones-even a mariachi band on the baseball diamond. Fey and human alike danced and cheered, humans in Halloween costumes, fey in the traditional garb of their clans.

On the lower end of the Common, police manned barricades separating the open field from the rise of the hill where the Civil War monument and fairy ring stood. Dylan showed his Guild badge to an officer to get us into a cordoned-off emergency path that wound its way through the crowds. Another security perimeter was set up around the monument at the top of the hill. Police, fire, and EMT communications units ranged in the rough circle, creating an island of relative calm in a sea of chaos. Marble statues representing war and peace stared down from the war monument’s pedestal in mute testament to the fact that things hardly ever truly change.

The essence within the fairy ring churned, a concentration more dense than the night Dylan and I argued. It was so intense, the unaided eye could see it. I didn’t need a sensing ability to see it. No one did.

Murdock waited near a temporary fence that was yet another barricade to the fairy ring. His body shield shimmered over his long camel-hair overcoat, the hardened crimson essence providing a level of safety I could only dream about. With all the colliding essence on the hill, any fey who noticed a body shield on a human probably dismissed it as a trick of the light. I didn’t like the grim look on his face. “They went in about ten minutes ago,” he said without waiting to be asked.

My chest tightened at the word “they.” I gripped the metal fencing and stared into the fairy ring. “Was Meryl all right?”

He cocked his head to listen to something on his radio before answering. “I didn’t see her myself. I’m told she was mobile but dazed-looking. Powell had a doctored Guild badge that got them into the inner perimeter. With all the Guild types in there, no one thought anything was wrong. They were last seen near the edge of that column of light. There was a bright flash, and they vanished.”

“I want to get in there,” I said. Murdock didn’t hesitate. Dylan and I followed him to a break in the barricade, and between their two official passes, no one tried to stop us.

Researchers and politicians roamed the restricted area around the fairy ring. The politicians were there for the photo op and the privilege of saying they could get in because someone thought they were someone important. The researchers were primarily fey, primarily from the Guild. Briallen and Nigel worked in separate groups, which was no surprise. Any other time, I would have loved to hear them argue back and forth about what was happening.

Flits flew around the thick essence like multicolored moths to a flame. Higher up in the air, fairies from the larger clans pressed closer. Fairies were air folk. Airborne essence attracted them and fed their essence-manipulating abilities. Drawn by the concentration of essence, the Taint had gravitated to the funnel, ambient wisps of the control spell that deepened in color as they collided and weaved together. A pressure headache sprang up behind my eyes. If the dark mass in my head didn’t like concentrated essence or the Taint, it definitely didn’t like the two of them together.

Murdock pointed to a spot that looked no different from the rest of the funnel. “This is where they went in.”

Shapes moved within the fog, faint impressions of bodies and faces. The funnel essence radiated a distinctive resonance unlike any I knew. I touched it and found not a misty vapor but a slightly repulsive texture like cool, pliant skin. I pushed, and it dimpled in under the pressure, not separating or tearing.

Briallen broke away from her group. She wore a wireless headset, an incongruity for her that I could not stop staring at. Briallen rejected most technotoys. She could. Lots of technology replicates what she can do with her own innate abilities. “It’s happening, Connor. The veil between worlds is thinning. Tara is secure, but there’s rioting at Stonehenge and Carnac.”

“There’s always rioting at Stonehenge,” Dylan muttered. He trailed along the ring, sparking little cantrips into the mist, fascination gleaming in his eyes.

“Did you see what happened with Meryl?” I asked.

Briallen stared up at the mist. “She had a binding spell on her. I was too far away to do anything. What I want to know is how the hell they went through.”

“A silver branch,” I said. “At least one of the items from the Met robbery was the real deal.”

Briallen had a bemused expression. “Before Convergence, we used to take things like that for granted. If the conditions were right, you could even pass through a portal into Faerie or TirNaNog or the Glass Isle without a silver branch. Part of me is thrilled the veil has thinned, and part of me is terrified.”

Dozens of flits popped into view, chattering excitedly as they swarmed around the fog. Briallen pause to listen in on her headset. “Word has spread. We’ll probably see more flits.”

Dylan returned from his circuit of the ring. “The Taint’s amplifying the veil.”

Briallen nodded. “That’s what I thought. What I don’t know is if people go through the veil, what effect the Taint will have on them. In the old days, people with unfinished business came back from TirNaNog, and they weren’t very nice about it.”

Something high up within the veil pressed outward and formed a dull gray lump on the swirling surface. The swelling receded, bulged again, and took on shape. The veil stretched as someone pushed against from the other side, the surface lightening from expansion until it was transparent enough to see a Danann fairy in an old-style court tunic. He struggled against the gray essence, pushing farther out, tendrils of mist elongating until they snapped with a silent flicker of light. He tumbled and caught air on long, translucent wings, hovering in confusion above our upturned faces. Shock registered on his face at the sight of the surrounding buildings. If the dated-ness of his clothes meant anything, he had never seen structures so tall. He muttered something in Old Irish that translated roughly as “Where the hell am I?”

He flew toward downtown.

“That was a dead guy?” Murdock asked.

“It depends on your definition of dead,” Dylan said.

I reached for the spot where the fairy had exited, but the surface closed before I could touch it. Another bulge formed and dissipated near my head, and I imagined someone on the other side trying the same thing I was. A hand rested on my shoulder. Briallen looking at me with shared concern. “She knows how to handle herself.”
