“Tell her Jaymes’s daughter, Opal, wishes to see her about an important matter.”

“Mara’s younger sister?” Interest flared in his gorgeous eyes.

Every man in Booruby knew and worshipped my sister. He looked close to her age of twenty-two, which probably meant they went to school together. I suppressed my annoyance. “Yes. And the matter is rather urgent.”

“Follow me.” He led me from the factory and into the cooler air. The man cut down an alley.

I hesitated on entering the quiet narrow street, remembering Zitora’s orders to be careful. But I decided the need to talk to Cesca was more important.

He stopped midway and knocked on a door, ushering me into a large storeroom filled with glasswares, crates and packing material. In the far corner an elderly woman sat behind an immense desk. Her thin skin clung to her face, revealing the contours of her skull beneath.

“This had better be imperative, Ulrick, or I won’t let you near my kilns for a season.” Her voice barked surprisingly strong.

I glanced at Ulrick with interest. He was the popping glassmaker. Unaware of my appraisal, Ulrick introduced me to his mother and retreated to the other side of the room to allow us more privacy. I explained to her about the Stormdancers orbs and the Brittle Talc.

“Nasty,” she said. “That horrid stuff almost ruined me. How can I help?”

I paused. Knowing I needed to choose my words with care, I gathered my thoughts. “Does anyone else know about the properties of Brittle Talc?”

“Yes. My children all know. We still check every shipment of lime for the contaminant.”

“And you have…?”

“Five children, three boys and two girls. Two daughters-in-law, one son-in-law and six grandchildren.” She beamed with pride. “They all work here, except the grandchildren and my daughter Gressa—she’s in the Moon Clan’s lands. All have been trained to work with glass. They make wonderful pieces. Well…most do.” Cesca glanced at Ulrick.

He sorted goblets, rolled them in cotton sheets and placed them into a wooden crate. His movements precise and efficient; the strong muscles in his arms and body apparent to me even though he wore plain gray overalls.

Cesca’s family created eight more suspects. I wouldn’t have time to talk to them all. “Has anyone asked you about Brittle Talc?”

“Besides my family?”

“Yes.”

“No.”

“But someone within your family was interested?”

The woman shot me a scathing look. “I hope you’re not implying one of my family members could be responsible for those brittle orbs.”

I rushed to assure her. “Of course not. But they may have talked to a friend or colleague. We’re just trying to find out who knows about the substance.”

“Ulrick had asked for more information about it. He wanted to use it. The boy likes to craft flawed pieces,” she said with a disdainful tone in her voice. “I told him if he ever brought Brittle Talc anywhere near Booruby, I would report him to the authorities. That is a criminal offence around here.” She pounded on her desk with a bony fist. “He never mentioned it again. Smart move.” Her pointed stare implied I should do the same.

Time to retreat. “Thank you for your time. If you think of anything else about this matter, could you please tell my father?”

She agreed, but, by her dismissive wave, I knew she wouldn’t pursue the subject. As I threaded through the crates, I spotted another one of Ulrick’s vases lying on the floor. I picked it up. The blue glass contained bubbles that had been stretched into long thin tubes. Marvelous. Tiny tremors rumbled in my fingers.

“Here,” Ulrick said, holding out his hand. “I’ll put that away.”

“Did you make it?”

A guarded expression cloaked his emotions. “Yes.”

“It’s fantastic.”

He rocked back in surprise. I stifled a laugh, remembering when Yelena had shocked me by being able to see the inner glow in my glass animals.

“But it’s unconventional. The seeds…” He shrugged.

“The bubbles enhance the piece.”

He gaped. I gave him the vase. When both of our hands touched the glass, it sang. A brief burst of surprised joy. If Ulrick heard the song, he didn’t give any indication.

I decided to risk being ridiculed. “What I also like about this vase is its joyful tune.”

Shock, fear and amazement flashed. He glanced at his mother, then grabbed my elbow, dragging me out to the alley.

“You heard it…sing?”

He hadn’t let go of my elbow.

“Only when you and I both touched it. Otherwise I feel its song.”

“Feel?” His fingers dug into my skin.

I pried his hand off. “Yes. It pops when I touch it.”

“But…but…” He yanked at his hair. “No one else can hear it. Or feel it. I don’t even know what it is.”

“It’s magic. Another magician should be able to feel the vibrations.”

Sudden recognition lit his eyes. “You’re the one who was invited to the Magician’s Keep! You’re the glass magician.”

I flinched. He used the same title as Blue Eyes.

He held up his vase. “Does this make me a magician?”

Probably a One-Trick Wonder like me, but I wasn’t going to say it aloud. “I don’t know. I’m meeting with Master Cowan soon. Perhaps you should talk to her. Can you leave for a few hours?”
