“That’s why she has a demon for a familiar,” Ceri said, eyes flicking nervously. “They had a contest. The loser became her familiar. He’s more of a caretaker, and he’s probably looking for her. They don’t like it when she slips his watch.”

The lights in my head started to go on, and my mouth dropped open. Seeing my understanding, Ceri tugged me down to her pentagram drawn in blood. Grabbing my wrist, she tuned it palm side up and aimed for my finger with her knife. “Hey!” I shouted, snatching my hand back.

Ceri looked at me, her lips pressed together. She was getting bitchy. That was good. It meant she thought she—we—might live through this. “Do you have a finger stick?” she snapped.

“No.”

“Then let me cut your finger.”

“You’re already bleeding,” I said. “Use your blood.”

“Mine won’t work,” she said from between gritted teeth. “It’s demon magic, and—”

“Yeah, I got it,” I interrupted. Her blood didn’t have the right enzymes, and thanks to some illegal genetic tinkering to save my life, I had survived being born possessing them.

The humming presence of the circle above us seemed to hesitate, and Newt made a sound of success. Ceri shuddered as she lost control of the middle circle, and Newt took it down. One thin, fragile circle left. I held out my hand—consumed with fear. Ceri’s eyes met mine, stress making her angular features beautiful. I only looked ugly when I got scared. Newt’s hand hovered over the last circle, smiling evilly as she muttered Latin. It had become a race.

Ceri made a quick swipe at my finger, and I jerked against the sting, watching a bead of red swell. “What do I do?” I asked, not liking this at all.

Blue eyes dropping, she turned my hand palm down and set it in the circle. The old oak seemed to vibrate, as if its stored life force were running through me, connecting me to the spinning of the earth and the burning of the sun. “It’s a public curse,” she said, her words falling over themselves. “The invocation phrase is mater tintinnabulum. Say it and Minias’s name in your thoughts, and the curse will put you through.”

“Don’t summon Minias,” Newt threatened, and I felt Ceri’s control over the last circle swell while the demon was distracted. “He’ll kill you faster than I will.”

“You aren’t summoning him, you’re asking for his attention,” Ceri said desperately. “The imbalance would normally go to you, but you can bargain with Newt’s location and he’ll take it. If he doesn’t, I will.”

It was a huge concession from the smut-covered elf. This was looking better and better, but the sun wasn’t up yet, and Newt looked ready to tear us apart. I didn’t think Ceri could hold her concentration much longer against a master demon. And I had to believe that the demons possessed a way to control this member of their species, otherwise they’d be dead already. If his name was Minias and he masqueraded as her familiar, then that’s the way it was.
