Chapter 1

Fern Millwood arrived at Silverstone Academy ten minutes early and still felt late.

A shy sun warmed the campus stone. Leaves rustled overhead, and a faint hum underfoot told Fern her nerves had followed her inside. She adjusted the strap of her sensible bag and reminded herself of the plan: introduce liminal studies basics and keep the syllabus simple without apologizing for existing. Easy.

The classroom was smaller and older than she expected. Chalk grooves scored the slate like memory lines. The quiet reminded Fern of boardrooms and elevators, those moments when everyone was waiting to judge. Fern set her notes on the lectern, smoothed the page twice, and smiled at the semicircle of students filtering in. Most looked curious, although one appeared bored. Tabitha Egan, if the roster was right, looked relieved to see her.

Pickles leapt onto the windowsill with a thump and glared at her.

You’re early. Suspicious.

Fern ignored him and launched into her welcome. She explained how to recognize thresholds, why students should listen before acting, and the importance of safety. Her voice grew steadier as she spoke. Maybe this would work..

When the bell chimed, the students drifted out with murmured goodbyes. Fern exhaled, a quiet victory. She gathered her notes, reached into her bag for reassurance and paused.

The familiar weight wasn’t there.

Her fingers searched again. The bag was empty except for pens and a wool scarf scratching her wrist. She checked the desk, but the space beside her notes was bare.

Pickles’ ears flattened. He sniffed once, twice, and fixed her with a look of offended certainty.

That, he seemed to say, wasn’t misplaced.

Fern swallowed. “Okay,” she whispered to the empty room. “That’s not ideal.”

She stood very still and listened. The faint vibration beneath the floorboards had changed. Not stronger, exactly. Just wrong enough that she noticed it.

Fern checked the lectern and chair again before searching the narrow shelf beneath the window where faculty left their mugs. Nothing. Everything remained exactly where it had been before class, except the guidebook.

She knelt and peered under the desk. A lost eraser. No guidebook.

Pickles hopped down, nose skimming the floor in a tight, irritated line. His whiskers twitched. He sneezed hard and backed away as if the air had offended him personally.

"Don’t do that," Fern murmured. "You’re making this worse."

Oh, am I? His tail lashed once. Because it smells like intention.

Fern straightened and replayed the class in her head. The door had remained open during the bell change, and a handful of students had lingered with questions. She’d set the book beside her notes without thinking, but she hadn’t left the room. Corporate life had taught her to watch the exits and keep important belongings within sight.

Footsteps passed in the hall. Fern poked her head out and caught two instructors mid-conversation, their voices low and faces tight. When they noticed her, the talk stopped. They offered guarded, polite nods before walking away.

“I’ll find it,” Fern told herself softly. The guidebook was old and irreplaceable, and it had never been careless with her.

Pickles leapt back to the windowsill and stared out toward the quad, ears pricked. The faint vibration beneath the floorboards briefly intensified before returning to its earlier rhythm.

Fern exhaled slowly. “Okay,” she said again, firmer this time. “First-day hiccup. We’ll ask around before we panic.”

Pickles did not look convinced.

Someone, his posture insisted, just crossed a line.

Fern closed the classroom door behind her and headed for the hall, already rehearsing how to ask for help without sounding like she didn’t belong.

The corridor felt cooler when Fern stepped into it. She could already imagine the questions. Did you misplace it? Are you sure you brought it? With them came the familiar urge to soften herself before anyone else could.

She squared her shoulders and started toward the administrative wing, steps measured. Doors opened and closed around her. Conversations slipped through the arches. Beneath it all, Fern still sensed that faint vibration under the stone, steady now, impossible to dismiss.

Pickles trotted at her side, uncharacteristically close. He glanced up at her, then ahead, as though mapping the space.

Welcome back, his silence seemed to say. Try not to disappear on your first day.

Fern huffed despite herself. "I’m not disappearing," she murmured. "I’m asking a question."

She turned the corner toward the library corridor. Whatever had happened to her grandmother’s guidebook, Fern no longer believed it was an accident.

Pickles stopped.

His ears flattened toward the floor.

Fern stopped too.

“What is it?”

He sniffed once, then looked toward the archive wing.

Whatever trace he had caught, it was coming from exactly where Fern had been heading.
