“Oh, good. It’s you,” a familiar female voice said from down the row. Nesta pivoted to discover Gwyn striding swiftly toward her, arms laden with books and coppery hair shimmering in the dim light.

Nesta didn’t bother to look pleasant as she lowered herself fully onto her feet.

Gwyn angled her head, as if finally realizing what she’d been doing. “Can’t you use magic to put it up on the shelf?”

“No.” The word was cool and sullen.

Gwyn’s brows twitched toward each other. “You don’t mean to tell me you’ve been shelving everything by hand?”

“How else would I do it?”

Gwyn’s teal eyes narrowed. “You have power, though, don’t you?”

“It’s none of your concern.” It was no one’s concern. She had none of the High Fae’s usual gifts. Her power—that thing—was utterly alien. Grotesque.

But Gwyn shrugged. “Very well.” She dumped her books right into Nesta’s arms. “These can go back.”

Nesta staggered under the books’ weight and glared.

Gwyn ignored the look, instead glancing around before lowering her voice. “Have you seen volume seven of Lavinia’s The Great War?”

Nesta scanned her memory. “No. I haven’t come across that one.”

Gwyn frowned. “It’s not on its shelf.”

“So someone else has it.”

“That’s what I was afraid of.” She released a dramatic breath.

“Why?”

Gwyn’s voice quieted into a conspiratorial whisper. “I work for someone who is very … demanding.”

Memory tugged at Nesta. Someone named Merrill, Clotho had told her the other day. Her right hand. “I take it you’re not fond of the person?”

Gwyn leaned against one of the shelves, crossing her arms with a casualness that belied her priestess’s robes. Again, she wore no hood and no blue stone atop her head. “Honestly, while I consider many of the females here to be my sisters, there are a few who are not what I would consider nice.”

Nesta snorted.

Gwyn again peered down the row. “You know why we’re all here.” Shadows swarmed her eyes—the first Nesta had seen there. “We all have endured …” She rubbed her temple. “So I hate, I hate to even speak ill of any one of my sisters here. But Merrill is unpleasant. To everyone. Even Clotho.”

“Because of her experiences?”

“I don’t know,” Gwyn said. “All I know is that I was assigned to work with Merrill and aid in her research, and I might have made a teensy mistake.” She grimaced.

“What manner of mistake?”

Gwyn blew out a sigh toward the darkened ceiling. “I was supposed to deliver volume seven of The Great War to Merrill yesterday, along with a stack of other books, and I could have sworn I did, but this morning, while I was in her office, I looked at the stack and saw I’d given her volume eight instead.”

Nesta reined in her eye rolling. “And this is a bad thing?”

“She’ll kill me when it’s not there for her to read today.” Gwyn hopped from foot to foot. “Which could be any moment. I got away the instant I could, but the book isn’t on the shelf.” She halted her fidgeting. “Even if I found the book, she’d spot me swapping it into the pile.”

“And you can’t tell her?” Gwyn couldn’t be serious about the killing thing. Though with the faeries, Nesta supposed it might be a possibility. Despite this place being one of peace.

“Gods, no. Merrill doesn’t accept mistakes. The book is supposed to be there, I told her it was there, and … I messed up.” The priestess’s face paled. She looked almost ill.

“Why does it matter?”

Emotion stirred in those remarkable eyes. “Because I don’t like to fail. I can’t …” Gwyn shook her head. “I don’t want to make any more mistakes.”

Nesta didn’t know how to unpack that statement. So she just said, “Ah.”

Gwyn went on, “These females took me in. Gave me shelter and healing and family.” Again, her large eyes darkened. “I cannot stand to fail them in anything. Especially someone as demanding as Merrill. Even when it might seem trivial.”

Admirable, though Nesta was loath to admit it. “Have you left this mountain since you arrived?”

“No. Once we come in, we do not leave unless it is time for us to depart—back to the world at large. Though some of us remain forever.”

“And never see daylight again? Never feel fresh air?”

“We have windows, in our dormitories.” At Nesta’s confused expression, she clarified, “They’re glamoured from sight on the mountainside. Only the High Lord knows about them, since they’re his spells. And you now, I suppose.”

“But you don’t leave?”

“No,” Gwyn said. “We don’t.”

Nesta knew she could let the conversation end there, but she asked, “And what do you do with the time you’re not in the library? Practice your … religious things?”

Gwyn huffed a soft laugh. “In part. We honor the Mother, and the Cauldron, and the Forces That Be. We have a service at dawn and at dusk, and on every holy day.”

Nesta must have made a face of distaste because Gwyn snorted. “It’s not so dull as all that. The services are beautiful, the songs as fair as any you’d hear in a music hall.”

That did sound rather interesting.

“I enjoy the dusk services,” Gwyn continued. “The music was always my favorite part of it, you know. I mean, not here. I was a priestess—an acolyte still—before I came here.” She added a shade quietly, “In Sangravah.”

The name sounded familiar to Nesta, but she couldn’t place it.

Gwyn shook her head, her face pale enough that her freckles stood out in stark relief. “I need to return to Merrill before she starts wondering where I am. And come up with some way to save my hide when she can’t find that book in the pile.” She jerked her chin to the books in Nesta’s hands. “Thanks for that.”

Nesta only nodded, and the priestess was gone, coppery-brown hair fading from sight.

She made it back to her cart with minimal wincing and grunting, though standing still for so long with Gwyn had made it nearly impossible for her to start walking again.

A few priestesses drifted by, either directly past her or on one of the levels above or below, utterly silent. This whole place was utterly silent. The only bit of color and sound came from Gwyn.

Would she remain here, locked beneath the earth, for the rest of her immortal life?

It seemed a shame. Understandable for what Gwyn must have endured, yes—what all these females had endured and survived. But a shame as well.

Nesta didn’t know why she did it. Why she waited until no one was around before she said into the hushed air of the library, “Can you do me a favor?”

She could have sworn she sensed a pause in the dust and dimness, a piqued interest. So she asked, “Can you get me volume seven of The Great War? By someone named Lavinia.” The House had no problem sending her food—perhaps it could find the tome for her.
