“I said hold it, Kyle.” Uncle Jeb’s voice was still relaxed, but the long rifle was gripped tightly in his hands now, and the barrels were pointed at Kyle’s back. Kyle was frozen just steps from me; his machete hung motionless in the air above his shoulder.

“Jeb,” the brother said, horrified, “what are you doing?”

“Step away from the girl, Kyle.”

Kyle turned his back to us, whirling on Jeb in fury. “It’s not a girl, Jeb!”

Jeb shrugged; the gun stayed steady in his hands, pointed at Kyle. “There are things to be discussed.”

“The doctor might be able to learn something from it,” a female voice offered gruffly.

I cringed at the words, hearing in them my worst fears. When Jeb had called me his niece just now, I’d foolishly let a spark of hope flame to life—perhaps there would be pity. I’d been stupid to think that, even for a second. Death would be the only pity I could hope for from these creatures.

I looked at the woman who’d spoken, surprised to see that she was as old as Jeb, maybe older. Her hair was dark gray rather than white, which is why I hadn’t noticed her age before. Her face was a mass of wrinkles, all of them turning down into angry lines. But there was something familiar about the features behind the lines.

Melanie made the connection between this ancient face and another, smoother face in her memory.

“Aunt Maggie? You’re here? How? Is Sharon —” The words were all Melanie, but they gushed from my mouth, and I was unable to stop them. Sharing for so long in the desert had made her stronger, or me weaker. Or maybe it was just that I was concentrating on which direction the deathblow was going to fall from. I was bracing for our murder, and she was having a family reunion.

Melanie got only halfway through her surprised exclamation. The much-aged woman named Maggie lunged forward with a speed that belied her brittle exterior. She didn’t raise the hand that held the black crowbar. That was the hand I was watching, so I didn’t see her free hand swing out to slap me hard across the face.

My head snapped back and then forward. She slapped me again.

“You won’t fool us, you parasite. We know how you work. We know how well you can mimic us.”

I tasted blood inside my cheek.

Don’t do that again, I scolded Melanie. I told you what they’d think.

Melanie was too shocked to answer.

“Now, Maggie,” Jeb began in a soothing tone.

“Don’t you ‘Now, Maggie’ me, you old fool! She’s probably led a legion of them down on us.” She backed away from me, her eyes measuring my stillness as if I were a coiled snake. She stopped beside her brother.
