Heir of Fire (Throne of Glass #3) by Sarah J. Maas

Rowan strode into the gaping maw of the cave mouth, his pale-gray cloak flapping behind him. “Hurry up.”

Pulling her own cloak tighter around her, she staggered after him. This was a bad sign. A horrible sign, actually, because whatever was in that cave…

She walked into the dark, following Rowan by the light on his hair, letting her eyes adjust. The ground was rocky, the stones small and worn smooth. And littered with rusted weapons, armor, and—clothes. No skeletons. Gods, it was so cold that she could see her breath, see—

“Tell me I’m hallucinating.”

Rowan had stopped at the edge of an enormous frozen lake, stretching into the gloom. Sitting on a blanket in its center, the chains around his wrists anchored under the ice, was Luca.

Luca’s chains clanked as he raised a hand in greeting. “I thought you’d never show. I’m freezing,” he called, and tucked his hands back under his arms. The sound echoed throughout the chamber.

The thick sheet of ice covering the lake was so clear that she could see the water beneath—pale stones on the bottom, what looked to be old roots from trees long dead, and no sign of life whatsoever. An occasional sword or dagger or lance poked up from the stones. “What is this place?”

“Go get him,” was Rowan’s answer.

“Are you out of your mind?”

Rowan gave her a smile that suggested he was, in fact, insane. She stepped toward the ice, but he blocked her path with a muscled arm. “In your other form.”

Luca’s head was angled, as if trying to hear. “He doesn’t know what I am,” she murmured.

“You’ve been living in a fortress of demi-Fae, you know. He won’t care.”

That was the least of her concerns, anyway. “How dare you drag him into this?”

“You dragged him in yourself when you insulted him—and Emrys. The least you can do is retrieve him.” He blew out a breath toward the lake, and the ice thawed by the shore, then hardened. Holy gods. He’d frozen the whole damn lake. He was that powerful?

“I hope you brought snacks!” Luca said. “I’m starving. Hurry up, Elentiya. Rowan said you had to do this as part of your training, and…” He prattled on and on.

“What is the gods-damned point of this? Just punishment for acting like an ass?”

“You can control your power in human form—keep it dormant. But the moment you switch, the moment you get agitated or angry or afraid, the moment you remember how much your power scares you, your magic rises up to protect you. It doesn’t understand that you are the source of those feelings, not some external threat. When there is an outside threat, when you forget to fear your power long enough, you have control. Or some control.” He pointed again to the sheet of ice between her and Luca. “So free him.”

If she lost control, if her fire got out of her… well, fire and ice certainly went well together, didn’t they? “What happens to Luca if I fail?”

“He’ll be very cold and very wet. And possibly die.” From the smile on his face, she knew he was enough of a sadist to let the boy go under with her.

“Were the chains really necessary? He’ll go right to the bottom.” A stupid, bleating kind of panic was starting to fill her veins.

When she held out her hand for the key to Luca’s chains, Rowan shook his head. “Control is your key. And focus. Cross the lake, then figure out how to free him without drowning the both of you.”

“Don’t give me a lesson like you’re some mystical-nonsense master! This is the stupidest thing I have ever had to—”

“Hurry,” Rowan said with a wolfish grin, and the ice gave a collective groan. As if it was melting. Though some small voice in her head told her he wouldn’t let the boy drown, she couldn’t trust him, not after last night.

She took one step closer to the ice. “You are a bastard.” When Luca was safely home, she would start finding ways to make Rowan’s life a living hell. She punched through her inner veil, the pain barely registering as her features shifted.

“I was waiting to see your Fae form!” Luca said. “We were all taking bets on when—” And on and on.

She scowled at Rowan, his tattoo even more detailed now that she was seeing it with Fae eyes. “It gives me comfort to know that people like you have a special place in hell waiting for them.”

“Tell me something I don’t already know.”

She gave him a particularly vulgar gesture as she stepped onto the ice.

As she took each tentative step—small ones at first—she could see the lake bottom sloping away into darkness, swallowing the spread of lost weapons. Luca had finally shut up.

It was only when she stepped past the visible edge of the rocky shelf and hovered over the dark depths that her breath hitched. She slid her foot, and the ice groaned.

Groaned, and cracked, spiderwebbing under her foot. She froze, gaping like a fool as the cracks spread wider and wider, and then—she kept moving. There was another crack beneath her boots. Did the ice move? “Stop it,” she hissed at Rowan, but didn’t dare look behind her.

Her magic shuddered awake, and she went still as death. No.

But there it was, filling up the spaces in her.

The ice emitted a deep groan that could only mean something cold and wet was coming her way really damn soon, and she took another step, if only because the way back seemed like it would shatter. She was sweating now—the magic, the fire was warming her from the inside out.
