Amren toyed with one of her black pearl earrings. “A messenger—and soldier-assassin. For a wrathful god who ruled a young world.”

I could feel the questions of the others brewing. Rhys’s eyes were near-glowing with them.

“Was Amren your name?” Nesta asked.

“No.” The smoke swirled in her eyes. “I do not remember the name I was given. I used Amren because—it’s a long story.”

I almost begged her to tell it, but soft footsteps thudded, and then—

“Oh.”

Elain started—enough so that I realized she couldn’t hear us. Had no idea we were here, thanks to the shield that kept sound from escaping.

It instantly dropped. But my sister remained near the stairs. She’d covered her nightgown with a silk shawl of palest blue, her fingers grappling into the fabric as she held herself.

I went to her immediately. “Do you need anything?”

“No. I … I was sleeping, but I heard …” She shook her head. Blinked at our formal attire, the dark crown atop my head—and Rhysand’s. “I didn’t hear you.”

Azriel stepped forward. “But you heard something else.”

Elain seemed about to nod, but only backed away. “I think I was dreaming,” she murmured. “I think I’m always dreaming these days.”

“Let me get you some hot milk,” I said, putting a hand on her elbow to guide her into the sitting room.

But Elain shook me off, heading back to the stairs. She said as she climbed the first steps, “I can hear her—crying.”

I gripped the bottom post of the banister. “Who?”

“Everyone thinks she’s dead.” Elain kept walking. “But she’s not. Only—different. Changed. As I was.”

“Who,” I pushed.

But Elain continued up the stairs, that shawl drooping down her back. Nesta stalked from Cassian’s side to approach my own. We both sucked in a breath, to say what, I didn’t know but—

“What did you see,” Azriel said, and I tried not to flinch as I found him at my other side, not having seen him move. Again.

Elain paused halfway up the stairs. Slowly, she turned to look back at him. “I saw young hands wither with age. I saw a box of black stone. I saw a feather of fire land on snow and melt it.”

My stomach dropped to the floor. One glance at Nesta confirmed that she felt it, too. Saw it.

Mad. Elain might very well have gone mad—

“It was angry,” Elain said quietly. “It was so, so angry that something was taken. So it took something from them as punishment.”

We said nothing. I didn’t know what to say—what to even ask or demand. If the Cauldron had done something to her as well …

I faced Azriel, exposing my palms to him. “What does that mean?”

Azriel’s hazel eyes churned as he studied my sister, her too-thin body. And without a word, he winnowed away. Mor watched the space where he’d been standing long after he was gone.

I waited until the others had left—Cassian and Rhys slipping away to ponder the possibilities or lack thereof of our would-be allies, Amren storming off to be rid of us entirely, and Mor striding out to enjoy what she deemed as her last few days of peace in this city, a brittleness still in her voice—before I cornered Nesta in the sitting room.

“What happened at the Hewn City—with you and Amren? You didn’t mention it.”

“It was fine.”

I clenched my jaw. “What happened?”

“She brought me to a room full of treasure. Strange objects. And it …” She tugged at the tight sleeve of her gown. “Some of it wanted to hurt us. As if it were alive—aware. Like … like in all those stories and lies we were fed over the wall.”

“Are you all right?” I couldn’t find any signs of harm on either of them, and neither had said anything to suggest—

“It was a training exercise. With a form of magic designed to repel intruders.” The words were recited. “As the wall will likely be. She wanted me to breach the defenses—find weaknesses.”

“And repair them?”

“Just find the weaknesses. Repairing is another thing,” Nesta said, her eyes going distant as she frowned at the still-open books on the low table before the fireplace.

I sighed. “So … that went right, at least.”

Those eyes went razor-sharp again. “I failed. Every time. So, no. It did not go right.”

I didn’t know what to say. Sympathy would likely earn me a tongue-lashing. So I opted for another route. “We need to do something about Elain.”

Nesta stiffened. “And what solution do you propose, exactly? Letting your mate into her mind to scramble things around?”

“I’d never do that. I don’t think Rhys can even … fix things like that.”

Nesta paced in front of the darkened fireplace. “Everything has a cost. Maybe the cost of her youth and immortality was losing part of her sanity.”

My knees wobbled enough that I took a seat on the deep-cushioned couch. “What was your cost?”

Nesta stopped moving. “Perhaps it was to see Elain suffer—while I got away unscathed.”

I shot to my feet. “Nesta—”

“Don’t bother.” But I trailed her as she strode for the stairs. To where Lucien was now descending the steps—and winced at the sight of her approach.

He gave her a wide berth as she stormed past him. One look at his taut face had me bracing myself—and returning to the sitting room.

I slumped into the nearest armchair, surprised to find myself still in my black dress as the fabric scraped against my bare skin. How long had I been back from the Hewn City? Thirty minutes? Less? And had the Prison only been that morning?

It felt like days ago. I rested my head against the embroidered back of the chair and watched Lucien take a seat on the rolled arm of the nearest couch. “Long day?”

I grunted my response.

That metal eye tightened. “I thought the Prison was another myth.”

“Well, it’s not.”

He weighed my tone, and crossed his arms. “Let me do something. About Elain. I heard—from my room. Everything that happened just now. It wouldn’t hurt to have a healer look her over. Externally and internally.”

I was tired enough that I could barely summon the breath to ask, “Do you think the Cauldron made her insane?”

“I think she went through something terrible,” Lucien countered carefully. “And it wouldn’t hurt to have your best healer do a thorough examination.”

I rubbed my hand over my face. “All right.” My breath snagged on the words. “Tomorrow morning.” I managed a shallow nod, rallying my strength to rise from the chair. Heavy—there was an old heaviness in me. Like I could sleep for a hundred years and it wouldn’t be enough.

“Please tell me,” Lucien said when I crossed the threshold into the foyer. “What the healer says. And if—if you need me for anything.”

I gave him one final nod, speech suddenly beyond me.

I knew Nesta still wasn’t asleep as I walked past her room. Knew she’d heard every word of our conversation thanks to that Fae hearing. And I knew she heard as I listened at Elain’s door, knocked once, and poked my head in to find her asleep—breathing.
