said.
She darted toward Torquin, pulled the tracking-signal detector from his gadget belt, and bolted toward the river. âCome on, letâs start!â
âHey!â Torquin cried out in surprise.
âLet them go, we have our hands full here!â Nirvana said.
Our footsteps made clouds of yellowish dust as we ran. Closer to the river, the ground was choked with scrubby grass and knots of small bushes. We stopped at the thicket of pine trees that stretched in both directions.
The ground sloped sharply downward. Below us, the Euphrates slashed a thick silver-blue S like a curved mirror through the countryside. To the north it wound around a distant settlement, then headed off toward mountains blurred by fog. To the south it passed by the Babylonian ruins before disappearing into the flatness. I scanned the riverbank, looking for signs of Marco.
âI donât see him,â Aly said.
I held up the tracker. Our blue dot locator and Marcoâs green one had merged. âHeâs here somewhere.â
âYo, Ocram!â Cass shouted. âCome out, come out, wherever you are!â
Rolling her eyes, Aly began walking down the slope toward the river. âHe might be hiding. If heâs playing a prank, I will personally dunk him in the water.â
âUnless he throws you in first,â I said.
I glanced quickly back over my shoulder to check on the others. Nirvana was struggling to push Professor Bhegadâs wheelchair across the rocky soil. He bounced a lot, complaining all the way. Torquin had taken off his studded leather belt and was trying to wrap it around Bhegad like a seat belt, causing his own pants to droop slowly downward.
They were going to take a while.
I started through the brush. It was dense and maybe three to five feet high, making it hard to see. As we moved forward, we kept calling Marcoâs name.
We stopped at the edge of a rocky ridge. None of us had seen this from the distance. It plunged straight downward, maybe twenty feet, to the river below. âOh, great,â Aly said.
I looked north and south. In both directions, the ridge angled downward until it eventually met the riverbed. âWeâll be okay if we go sideways,â I said.
I went to the edge and looked over. I eyed the tangle of trees, roots, and bushes along the steep drop. Since Marco had taught us to rock climb, steep embankments didnât scare me as much as they used to. This looked way easier than climbing Mount Onyx.
âMaybe thereâs a shortcut,â I said. Quickly I stepped over the edge, digging my toes into a sturdy root. I turned so my chest would be facing the cliff. Holding on to a branch, I descended another step.
âWhoa, Jack, donât,â Cass said.
I laughed. âThis is eaââ
My foot slipped. My chin hit the dirt. I slid downward, grasping frantically. My fingers closed around branches and vines. I pulled out about a dozen, and a dozen more slipped through my hand. I felt my foot hit a root and I caromed outward, landing at the bottom, hard on my back. ââsy,â I continued.
âI think Iâll look for a path,â Cass called down.
Alyâs face was going in and out of focus. I could have sworn she was trying to hold back a smile. âAre you hurt?â
âJust resting.â I closed my eyes and lay still, my breath buzzsawing in my chest. I heard a dull moan, and I figured it must have been my own voice.
But when I heard it again, my eyes blinked open.
I sat up. Aly and Cass were just below the crest of the ridge, trying to make their way down. They were both shouting. But my eyes were focused on a thick, brownish-green bush, maybe ten yards away.
A pair of shoes jutted from underneath.
