“Not really,” she murmurs, running her hands over the stones’ surfaces. “This is the healing stone Henri and I used at the school,” she says, pointing out a flat, black rock I’ve seen before. Then she freezes, a faint gasp escaping her lips. Sam and I exchange confused expressions. She lifts a pale yellow stone, its surface waxy and smooth, from the Chest and holds it up to the light. “Oh my God,” she marvels, flipping it over.

“Tell me,” I prod. She looks me right in the eyes.

“Xitharis,” she says. “It comes from our first moon.”

She brings the small stone to her forehead, squeezing her eyes shut. The faint yellow shade of the stone darkens slightly. She opens her eyes and hands the stone to me. I frown and take it from her, my fingertips grazing the palm of her hand. Sam inhales sharply.

“What the . . .” He looks terrified, groping for me like he’s blind.

“What’s going on?” I ask, slapping Sam’s hands away from my face.

“You’re invisible,” Six says quietly. I look down at my lap, and it’s true: I’ve completely vanished. I drop the Xitharis on the floor like a hot potato, and instantly become visible.

“The Xitharis,” Six explains, “allows one Garde to transfer a Legacy to another, but only for a short period of time. An hour, I think, maybe two. I can’t say for sure. All you have to do is charge it by focusing your energy on the stone. Put it to your forehead, and bam, it’s ready to go.”

“Charge it, like a battery?” Sam asks.

“Exactly, and it won’t start using the Legacy until it’s touched again.”

I look at the stone. “Sweet. Looks like somebody other than you is taking a trip into town.”

“And somebody other than you is going to be resistant to fire,” she says playfully.

“If you’re nice to me, then it’s definitely a possibility,” I say.

Sam picks the stone up and clenches his entire body in deep concentration. Nothing happens. “Oh come on,” he says to the stone. “I promise to use it for the power of good. No girls’ locker rooms, I swear.”

“Sorry, Sam,” Six says. “I’m pretty sure this stuff only works on us.”

He sets the Xitharis down and we dig through the rest of the Chest to see if anything else is activated by touch; but after an hour of studying and holding all seventeen artifacts, blowing hot air on them, squeezing them tightly, nothing else engages aside from the glowing crystal wrapped in the towel, the larger oblong crystal with the smoky center, and the solar system still rotating above us. The healing stone, however, does cure the cuts and bruises Six has been stamping my body with.
