that it took a lot less energy to stay in the valleys between the dunes when they could, so she began cutting a slower, yet less exhausting zigzag route across the desert.
As she walked, the towels around her feet began to loosen and grains of sand slipped in and got caught between her toes, despite how tight Thorne had tied the ropes of hair. The soles of her feet began to burn and a cramp was threatening to overtake her left foot from the constant grab and release of her toes on the unstable ground. Her legs ached. Cress’s body began to rebel as they rambled up yet another dune. Her thighs would burn as she crested one more hill—but then her shins would cry out as they descended the other side. Her silly fitness routines aboard the satellite hadn’t prepared her for this.
But she did not complain. She panted a great deal. She swiped at the sweat drops on her temples. She clenched her jaw against the hurt. But she did not complain.
At least she could see, she reminded herself. And at least she didn’t have to carry the supplies. She heard Thorne switch shoulders from time to time, but he didn’t complain either.
Sometimes when they struck a flat spot, she closed her eyes to see how long she could go without opening them. Vertigo would set in almost immediately. Panic would blossom at the base of her spine and crawl up it until she was sure each new step would bring her in contact with a rock or a small hill and she would stumble face-first into the sand.
The fourth time she did it, Thorne asked her why they kept slowing down. She kept her eyes open after that.
“Do you need to take a break?” Thorne asked, hours later.
“N-no,” she huffed, her thighs burning. “We’re almost to the top of this dune.”
“Sure? No point passing out from exhaustion.”
She breathed a sigh of relief upon reaching the top of the dune, but dread quickly took its place. She didn’t know why she’d expected this dune to be different from the dozens they’d already crested. She didn’t know why she’d been thinking that this must have marked the end of the desert, because she didn’t think she could go much farther.
But it was not the end. The world was made of more dunes, more sand, more nothingness.
“Really. Let’s take a break,” Thorne said, setting down the pack and stabbing the cane into the ground. He spent a moment working the kinks from his shoulders, before hunching over and undoing the bundle’s knot. He handed Cress one of the water bottles and took another for himself.
“Shouldn’t we ration it?” she asked.
He shook his head. “It’s best to drink when we’re thirsty, and just try to keep sweating to a minimum—as much as possible. Our bodies will be better able to maintain hydration that way, even if we do run out of water. And we should avoid eating until we find another water source. Digestion uses up a lot of water too.”
“That’s fine. I’m not hungry.” Which was true—the heat seemed to have stolen what appetite she’d had.
When she’d drank all she could, Cress handed the bottle back to Thorne and fantasized about collapsing into the sand and going to sleep, but she dared not, fearing she would never get up again. When Thorne lifted the pack, she took off down the hill without question.
“What do you think is happening on your ship?” Cress asked as they descended the hill. The question had been echoing in her mind for hours, but the water had finally made her capable of speech. “Do you think Mistress Sybil…”
“They’re fine,” Thorne said, with unrelenting confidence. “I pity the person who goes up against Wolf, and Cinder’s made of tougher stuff than people realize.” A pause, before a hearty laugh burst through the quiet desert air. “Literally, in fact.”
“Wolf. That must be the other man on the ship?”
“Yes, and Scarlet is his … well, I don’t really know what they call themselves, but he’s lunatic-crazy for her. Scarlet’s not a bad shot, herself. That thaumaturge had no idea what she was walking into.”
Cress hoped he was right. Mistress Sybil had found them because of her, and the guilt was as painful as the deep aches in her bones.
“So how did a girl born on Luna get stuck in a satellite and become an Earthen sympathizer, anyway?”
She wrinkled her nose. “Well. When my parents found out I was
