the highest temperatures yet, Thorne had also promised a respite from walking.
“All right,” Thorne finally said, as if the words were being dragged up from his throat. “That’s enough. Let’s rest until the temperature goes down again.”
Cress groaned with relief. She would have kept walking all day if he had asked it of her, but how glad she was that he hadn’t.
“Do you see any shade at all? Or someplace that looks like it might be shaded when the sun starts going down?”
Cress squinted across the dunes. Though there was some shade over the occasional hillock, at high noon it was almost nonexistent. Still, they were coming up on a big hill that would soon cast some shadows—it was the best they could do.
“This way,” she said, spurred on by the promise of rest.
But as they crested one more dune, her eye caught on something in the distance. She gasped, grabbing Thorne’s arm.
“What is it?”
She gaped at the glorious sight, struggling to find words to describe it. Blue and green, a stark contrast against the orange desert sand. “Water. And … and trees!”
“An oasis?”
“Yes! It must be!”
Relief spilled over her. She began to tremble with the promise of shade, water, rest.
“Come on—it isn’t far,” she said, plowing through the sand with renewed energy.
“Cress. Cress, wait! Reserve your energy.”
“But we’re almost there.”
“Cress!”
She barely heard him. Already she could imagine the cool water slipping down her throat. The breeze beneath a palm’s canopy. Maybe there would be food, some strange tropical Earthen food she’d never tasted, that would be juicy and crisp and refreshing …
But mostly she thought of collapsing into a nice patch of shade, cooled and protected from the sun, and sleeping until nighttime brought the return of cooler temperatures and endless stars.
Thorne trooped after her, having given up trying to make her stop, and soon she realized she was being cruel to make him go so fast. She slowed a little, but kept her eyes on the lake that shimmered at the base of a dune.
“Cress, are you sure?” he asked when he’d caught his breath.
“Of course I’m sure. It’s right there.”
“But … Cress.”
Her pace slowed. “What’s wrong? Are you hurt?”
He shook his head. “No, just … all right. All right, I can keep up. Let’s get to this oasis.”
She beamed and grabbed his free hand, leading him over the desert’s ripples and tides. Her fantasies took over, eclipsing her fatigue. The towels had nearly rubbed the soles of her feet raw and her calves were sunburned where her sheet didn’t protect them and her brain was swirling with thirst, but they were close. So close.
And yet, as she slipped along the powdery sand, it seemed that the oasis never came any closer. It always lingered at the horizon, as if the shimmering trees were receding with each step she took.
She plowed on, desperate. The distances were deceptive, but soon they would reach it. If only they kept moving. One step at a time, one foot in front of the other.
“Cress?”
“Captain,” she panted, “it’s … it isn’t far.”
“Cress, is it getting any closer?”
She stumbled, her pace slowing drastically until she stopped, gasping for breath. “Captain?”
“Do you see it getting closer? Do the trees look bigger than they were before?”
She squinted at the water, the trees, the most gorgeous sight, and swiped her sleeve over her face. She was so hot, but no sweat was left behind on the cloth.
The truth was so painful, she almost didn’t have the strength to say it. “N-no. But that’s … how could…”
Thorne sighed, but it was not a disappointed sigh, merely resigned. “It’s a mirage, Cress. It’s the light playing tricks on your eyes.”
“But … I can see it. There are even islands in the lake, and trees…”
“I know. Mirages always seem real, but you’re only seeing what you want to see. It’s a trick, Cress. It’s not there.”
She was mesmerized by how the water rippled in little waves, how the trees trembled like a breeze was teasing their branches. It looked so real, so tangible. She could almost smell it, almost taste the cool wind blowing toward her.
Cress barely managed to stay standing, her fear of being scorched by the hot sand alone giving her the strength.
“It’s all right. Lots of people see mirages in the desert.”
“But … I didn’t know. I should have known. I’ve heard stories, but I didn’t … I didn’t think it could look so real.”
Thorne’s fingers brushed against the sheet, finding her hand. “You’re not going to
