“I had a close call with a Dark Hallow, and they make me too sick to function if I get too close.”

He leaned forward, elbows on his knees, and stared at me with fascination. “Now that was a celestial choir of truth, lass! You saw a Dark Hallow? Which one?”

“How do you know about the Dark Hallows? Who are you and what’s your involvement in this?” I didn’t need any more mystifying men in my life.

“How much truth will you give me?”

I hesitated only briefly. Of all the men I’d met in Dublin, he seemed the most like me; essentially normal, but afflicted with an unwanted, life-altering talent. “As much as I can, if you do the same.”

He nodded, satisfied, then settled back in his chair. “I come from a clan that, in ancient times, served the Fae.”

The Keltar, Christian told me, had once been High Druids to the Tuatha Dé Danaan, many thousands of years ago, during that brief time in which the Fae had attempted to play nice and coexist with man. Something had happened that shattered the fragile peace—he skimmed over this part—but whatever it was had caused Fae and Man to go their separate ways, and not amicably.

A Compact was negotiated to permit both races to exist on the same planet but keep the realms separate, and the Keltar were given the duty of performing certain rituals to maintain the walls between them. Over the millennia, they performed them faithfully with few exceptions, and if they failed in some small way, they always managed to make up for it in the nick of time.

But in recent years, the rituals stopped going as expected. On those preappointed nights of the year when the Keltar were to perform their magic, some other dark magic had risen up and prevented the pledge from being reinforced, and the tithe from being fully paid. Although this other magic hadn’t been able to collapse the walls between our worlds, it had seriously weakened them. Christian’s uncles believed the walls would not hold through another incomplete ritual. The queen of the Seelie, Aoibheal, who in the past had always appeared in times of crisis, had yet to be seen, although they’d invoked her by every spell they had at their disposal.

I was riveted by the story. The thought that, for thousands of years, a clan in the Highlands of Scotland had been protecting Mankind from the Fae fascinated me. Especially if they were all like Christian: gorgeous, sexy, self-possessed. It was comforting to know there were other bloodlines out there in the world with special, unusual powers. I wasn’t alone in my awareness of what was happening to our world. I’d found someone besides Barrons who had more information than me, and he was willing to share it!

“My uncles believe something has happened to the queen,” he said, “and as her power diminishes, another’s grows. The walls continue to weaken, and if we don’t figure out something by the time the next ritual must be performed, they’ll come down.”

“What’ll happen then?” I asked in a hushed voice. “Will the Compact be broken?”

“My uncles believe the Compact already is broken, that the walls are holding only because of the increasing tithes they keep paying. Fae magic is strange stuff.” He paused then said tightly, “At the last rites, we had to use blood, Keltar blood, in a pagan ritual. It’s unheard of. We’ve never used blood before. Uncle Cian knew how to do it. It was dirty magic. I could feel it. What we did was wrong but it was the only thing we could do.”

I understood that feeling. What I’d done to Jayne would never sit entirely well with me, but I’d been unable to think of an alternative. It hadn’t been dirty magic, just dirty tea. Manipulative. Ruthless. But I’ve begun to understand that you can only afford to play nice when there’s not much at stake. “And if the walls come down completely?” I reiterated my earlier question. I wanted to know just how bad things might get.

“When the Fae walked among us before, only the Seelie did. The Unseelie have been imprisoned for so long that mere whispers of myths remain. If the walls come down completely, all the Unseelie will be freed, not just the lower castes that are currently managing to get through somehow. The most powerful of the Unseelie Royal Houses will escape.” He paused and when he spoke again, his voice was low, urgent. “Myth equates the heads of those four houses, the dark princes, with the Four Horsemen of the Apocalypse.”

I knew who they were: Death, Pestilence, War, and Famine. The Unseelie I’d seen so far were bad enough. I had no desire to ever encounter a royal dark Fae.

“It’ll get bad, Mac. They’ll turn our world into a living nightmare. My uncles believe the Seelie may not be able to reimprison the Unseelie if they escape.”
