I winced. “Sorry.”

She smiled, but I caught a grimace when she didn’t realize I was watching. Ceri was the nicest person I knew, giving treats to children and squirrels and being polite to door-to-door solicitors, but she had little patience when it came to teaching. Her abrupt temper didn’t mix well with my scattered concentration and haphazard study habits.

Flushing, I set my plate aside and slid the cool, sinking-into-my-legs feeling of my scrying mirror onto my lap. I wasn’t hungry anymore, and Ceri’s impatience was making me feel stupid. I reached for my magnetic chalk, nervous. “I’m not very good at this,” I muttered.

“Which is why you’re doing it in chalk, then etching it in,” she said. “Go on, let’s see it.”

I hesitated, looking at the big blank expanse of glass. Crap.

“Come on, Rache!” Jenks coaxed, dropping down to land on the mirror. “Just follow me.” Wings going full tilt, he started to pace in a wide circle.

I arranged myself to follow his lead, and Ceri said, “Pentagram first.”

I jerked my hand from the glass. “Right.”

Jenks looked up at me as if in direction, and I felt a sinking sensation. Ceri set her plate down, her disgust obvious. “You don’t know a thing about this, do you?”

“Jeez, Ceri,” I complained, watching Jenks flit furtively to steal the smear of honey on Ceri’s spoon. “I haven’t actually finished any ley line classes. I know my pentagrams suck dishwater, and I have no idea what those symbols mean or how to draw them.” Feeling dumb, I grabbed my wineglass—the white wine, not the red Ceri had brought out—and took a sip.

“You shouldn’t drink when you work magic,” Ceri said.

Frustrated, I set the glass down almost hard enough to spill. “Then why is it out here?” I said, a shade too loudly.

Jenks eyed me in warning, and I puffed my air out. I didn’t like feeling stupid.

“Rachel,” the woman said softly, and I grimaced at the chagrin in her voice. “I’m sorry. I shouldn’t expect you to have the skills of a master when you’re only starting out. It’s just…”

“…a stupid pentagram,” I finished for her, trying to find the humor in it.

She reddened. “Actually, it’s merely that I wanted to get this done tonight.”

“Oh.” Embarrassed, I looked at the blank mirror, my reflection a gray shadow peering back at me. It was going to look like crap. I knew it.

“The wine is a carrier for the invocation blood, also washing the salt off the mirror when you’re done,” Ceri said, and my gaze went to the bucket, now understanding why she’d brought it out. “The salt acts as a leveler, removing the excess intent in the lines you scribe in the glass as well as bringing the acidic content of the yew back to a neutral state.”

“Yew is toxic, not acidic,” I said, and she nodded apologetically.

“But it will etch the glass once you coat it in your aura.”
