intellectus and realized that Mac and Sarissa were bringing up the rear. That wouldn’t do. I still didn’t know the role they were playing in this game. “Mouse,” I called. “Take rear guard, in case those hounds circle around and try to sneak up on us.”
The big furball made a huffing sound, an exhalation somewhere between a bark and a sneeze, but chewier. Heh. Chewie. I reminded myself to keep track of Mac and Sarissa as we went, but I felt better once Mouse was back there. Intellectus was handy as a reference guide, but not as an early-warning system. If either of them tried anything shady, the shaggy Tibetan guardian was probably the one most likely to notice first, anyway. Might as well have him close.
“Who’s up there?” Karrin asked, her voice low and tense.
“Faerie Queens, I think. Plural.”
“Whoa,” Thomas said. “Why?”
“Complicated, no time,” I said. “No one does anything until I do. Don’t even talk. If the balloon goes up, go after whoever I light up first. After that, improvise.”
Then I continued, increasing the pace a little. The trees near the crown of the island were older, thicker, and taller. The spreading canopy of their branches had shaded out most of the brush beneath them, and the ground was easier to move across, being mostly an irregular, soggy carpet of years and years’ worth of fallen leaves. The scent of molds was thick as we went through, disturbing them.
We emerged into the clearing at the top of the hill, and I stopped in my tracks six inches before I would have come out of the shadow of the forest. Thomas bumped into me. I looked partly over my shoulder with a little push of air through my teeth. He elbowed me in the lower back.
The hilltop had been closed in a circle of starlight.
I didn’t know how else to describe it. I didn’t know what I was looking at. Twelve feet off the ground was a band of illumination, glowing rather than glaring, something that filled the hilltop with gentle light, like an enormous ring floating above the earth. It was of precise width, as if drawn with a compass, and I knew that it was exactly one foot thick—twelve inches. The color was something I had never seen before, changing subtly moment to moment, holding silver and blue and gold, but it wasn’t any of those things and . . . and words fail. But it was beautiful, like love, like music, like truth, something that passed through the eyes and plunged straight to the soul. Gentle, softly glowing light slid from the outer edge of the circle like a sheet of water from an elegant fountain, falling to the ground in a slow-motion liquid curtain of pure light, hiding what was behind it.
I felt the grasshopper move up beside me, her eyes wide. “Boss,” she whispered. “This would make my mom talk in her church voice. What are we looking at?”
“Merlin’s work, I think,” I breathed. “That circle. I think it’s part of the island’s architecture.”
“Wow.”
“I . . . It’s beautiful,” Sarissa murmured. “I’ve never seen anything like it. And I’ve been looking at incredible things my whole life.”
I spoke something I was certain was true in the same moment that I understood it. “It had to be beautiful. It had to be made from beauty. There is too much ugly inside for it to be made of anything else.”
“What do you mean, ugly?” Karrin asked, her voice hushed.
“Later,” I said. I shook my head and blinked my eyes several times. “City to save.” I tried to find something about the circle in my intellectus, but I had apparently already learned everything I could learn about it that way. I knew its exact dimensions; I knew it was part of the structure of the massive spell that made the Well exist. And that was it. It was like the entire thing had been . . . classified, top secret, need-to-know only—and apparently I didn’t need to know.
Which, I supposed, made sense. We were talking about a massive security system.
Molly stooped and picked up a rock. She gave it a gentle underhand toss at the wall of light and it passed through without making a ripple. “Safe?” she asked.
“I doubt it. Give me something that isn’t a part of the island,” I said.
I heard her slip her backpack off her shoulder and open a zipper. Then she touched my arm and passed me a granola bar wrapped
