Kingdom of Ash (Throne of Glass #7) by Sarah J. Maas

The roaring of the oncoming wave became deafening, even from miles away.

Still Elide and Lorcan raced, Farasha passing horse after horse after horse.

Even up here, would they escape the wave’s reach? Rowan dared to survey the battlements, to assess if he needed to get the others, needed to get Aelin, to higher ground.

But Aelin was not at his side.

She was not on the battlement at all.

Rowan’s heart halted. Simply stopped beating as a ruddy-brown ruk dropped from the skies, spearing for the center of the plain.

Arcas, Borte’s ruk. A golden-haired woman dangling from his talons.

Aelin. Aelin was—

Arcas neared the earth, talons splaying. Aelin hit the ground, rolling, rolling, until she uncoiled to her feet.

Right in the path of that wave.

“Oh gods,” Fenrys breathed, seeing her, too.

They all saw her.

The queen on the plain.

The endless wall of water surging for her.

The keep stones began shuddering. Rowan threw out a hand to brace himself, fear like nothing he had known ripping through him as Aelin lifted her arms above her head.

A pillar of fire shot up around her, lifting her hair with it.

The wave roared and roared for her, for the army behind her.

The shaking in the keep was not from the wave.

It was not from that wall of water at all.

Cracks formed in the earth, splintering across it. Spiderwebbing from Aelin.

“The hot springs,” Chaol breathed. “The valley floor is full of veins into the earth itself.”

Into the burning heart of the world.

The keep shook, more violently this time.

The pillar of fire sucked back into Aelin. She held out a hand before her, her fist closed.

As if it would halt the wave in its tracks.

He knew then. Either as her mate or carranam, he knew.

“Three months,” Rowan breathed.

The others stilled.

“Three months,” he said again, his knees wobbling. “She’s been making the descent into her power for three months.”

Every day she had been with Maeve, bound in iron, she had gone deeper. And she had not tapped too far into that power since they’d freed her because she had kept making the plunge.

To gather up the full might of her magic. Not for the Lock, not for Erawan.

But for Maeve’s death blow.

A few weeks of descent had taken her powers to devastating levels. Three months of it …

Holy gods. Holy rutting gods.

And when her fire hit the wall of water now towering over her, when they collided—

“GET DOWN!” Rowan bellowed, over the screaming waters. “GET DOWN NOW!”

His companions dropped to the stones, any within earshot doing the same.

Rowan plummeted into his power. Plummeted into it fast and hard, ripping out any remaining shred of magic.

Elide and Lorcan were still too far from the gates. Thousands of soldiers were still too far from the gates as the wave crested above them.

As Aelin opened her hand toward it.

Fire erupted.

Cobalt fire. The raging soul of a flame.

A tidal wave of it.

Taller than the raging waters, it blasted from her, flaring wide.

The wave slammed into it. And where water met a wall of fire, where a thousand years of confinement met three months of it, the world exploded.

Blistering steam, capable of melting flesh from bone, shot across the plain.

With a roar, Rowan threw all that remained of his magic toward the onslaught of steam, a wall of wind that shoved it toward the lake, the mountains.

Still the waters came, breaking against the flames that did not so much as yield an inch.

Maeve’s death blow. Spent here, to save the army that might mean Terrasen’s salvation. To spare the lives on the plain.

Rowan gritted his teeth, panting against his fraying power. A burnout lurked, deadly close.

The raging wave threw itself over and over and over into the wall of flame.

Rowan didn’t see if Elide and Lorcan made it into the keep. If the other soldiers and riders on the plain stopped to gape.

Princess Hasar said, rising beside him, “That power is no blessing.”

“Tell that to your soldiers,” Fenrys snarled, standing, too.

“I did not mean it that way,” Hasar snipped, and awe was indeed stark on her face.

Rowan leaned against the battlements, panting hard as he fought to keep the lethal steam from flowing toward the army. As he cooled and sent it whisking away.

Solid hands slid under his arms, and then Fenrys and Gavriel were there, propping him up between them.

A minute passed. Then another.

The wave began to lower. Still the fire burned.

Rowan’s head pounded, his mouth going dry.

Time slipped from him. A coppery tang filled his mouth.

The wave lowered farther, raging waters quieting.

Then roaring turned to lapping, rapids into eddies.

Until the wall of flame began to lower, too. Tracking the waters down and down and down. Letting them seep into the cracks of the earth.

Rowan’s knees buckled, but he held on to his magic long enough for the steam to lessen. For it, too, to be calmed.

It filled the plain, turning the world into drifting mist. Blocking the view of the queen in its center.

Then silence. Utter silence.

Fire flickered through the mist, blue turning to gold and red. A muted, throbbing glow.

Rowan spat blood onto the battlement stones, his breath like shards of glass in his throat.
