Jared didn’t make allowances for me the way Jeb had. He stalked off into the black tunnel without pausing for me to catch up.

It was hard—he didn’t make much noise and he didn’t guide me, so I had to walk with one hand in front of my face and one hand on the wall, trying not to run into the rock. I fell twice on the uneven floor. Though he did not help me, he did wait till he could hear that I was on my feet again to continue. Once, hurrying through a straighter section of the tube, I got too close and my searching hand touched his back, traced across the shape of his shoulders, before I realized that I hadn’t reached another wall. He jumped ahead, jerking out from under my fingers with an angry hiss.

“Sorry,” I whispered, feeling my cheeks turn warm in the darkness.

He didn’t respond, but sped his pace so that following was even more difficult.

I was confused when, finally, some light appeared ahead of me. Had we taken a different route? This was not the white brilliance of the biggest cavern. It was muted, pale and silvery. But the narrow crevice we’d had to pass through seemed the same.… It wasn’t until I was inside the giant, echoing space that I realized what caused the difference.

It was nighttime; the light that shone dimly from above mimicked the light of the moon rather than the sun. I used the less-blinding illumination to examine the ceiling, trying to ferret out its secret. High, so very high above me, a hundred tiny moons shone their diluted light toward the dim, distant floor. The little moons were scattered in patternless clusters, some farther away than others. I shook my head. Even though I could look directly at the light now, I still didn’t understand it.

“C’mon,” Jared ordered angrily from several paces ahead.

I flinched and hurried to follow. I was sorry I’d let my attention wander. I could see how much it irritated him to have to speak to me.

I didn’t expect the help of a flashlight when we reached the room with the rivers, and I didn’t receive it. It was dimly lit now, too, like the big cave, but with only twenty-odd miniature moons here. Jared clenched his jaw and stared at the ceiling while I walked hesitantly into the room with the inky pool. I guessed that if I stumbled into the fierce underground hot spring and disappeared, Jared would probably see it as a kind intervention of fate.

I think he would be sad, Melanie disagreed as I edged my way around the black bathing room, hugging the wall. If we fell.

I doubt it. He might be reminded of the pain of losing you the first time, but he would be happy if I disappeared.
