“Uh... ," Ivy stammered, and I glanced up to see her eyes wide in consideration.
"I'm kidding," I said. "It passed the lethal-amulet test, remember?"
"Not that. You keep it in your underwear drawer?"
I hesitated, wondering why I was embarrassed. "Well, where do you put your elven magic?" I asked.”

“Magic comes from the heart, from your feelings, your deepest expressions of desire. That's why black magic is so easy—it comes from lust, from fear and anger, from things that are easy to feed and make grow. The sort I do is harder. It comes from something deeper than that, a truer and purer source—harder to tap, harder to keep, but ultimately more elegant, more powerful. My magic. That was at the heart of me. It was a manifestation of what I believed, what I lived. It came from my desire to see to it that someone stood between the darkness and the people it would devour. It came from my love of a good steak, from the way I would sometimes cry at a good movie or a moving symphony. From my life. From the hope that I could make things better for someone else, if not always for me. Somewhere, in all of that, I touched on something that wasn't tapped out, in spite of how horrible the past days had been, something that hadn't gone cold and numb inside of me. I grasped it, held it in my hand like a firefly, and willed its energy out, into the circle I had created with the spinning amulet on the end of its chain.”

“Oh, good, it worked,” Archer said, his ghostly face relieved. Unlike Elodie, his voice came in loud and clear, and so familiar that my heart broke all over again.
I stood frozen, my back against the door. Even though he was faint, I could see him smirk.
“Um…Mercer? Haven’t seen you in nearly a month. I was expecting something like, ‘Oh, Cross, love of my heart, fire of my loins, how I’ve longed—’”
“You’re dead,” I blurted out, pressing a hand against my stomach. “You’re a ghost, and you think—”
All the humor disappeared from his face, and he held up both hands. “Whoa, whoa, whoa. Not dead. Promise.”
My heart was still hammering. “Then what the heck are you?”
Archer almost looked sheepish as he reached inside his shirt and pulled out some kind of amulet on a thin silver chain. “It’s a speaking stone. Lets you appear to people kind of like a hologram. You know. ‘Help me, Sophie-Wan Kenobi, you’re my only hope.’”
“Did you steal it from the cellar at Hecate, too?” Archer had collected all sorts of magical knickknacks back when we had cellar duty at Hex Hall.
“No,” he said, offended. “I found it at a…store. For magical stuff. Okay, yes, I stole it from the cellar.”

“That did it. I'd gone through a lot in the past few days. Everyone I met seemed to want a piece of me: djinn, magicians, humans...it made no difference.I'd been summoned, manhandled, shot at, captured, constricted, bossed about and generally taken for granted. And now, to cap it all, this bloke is joining in too, when all I'd been doing was quietly trying to kill him.”
