Beneath the soggy leaves coating Oakwald’s floor, loose gray stones made the slope treacherous, the towering oaks stretching too high above for her to grip any branches should she tumble down. Braving the potential fall in favor of speed, Elide scrambled over the lip of the craggy summit, her leg twanging with pain as she slumped to her knees.

Forested hills rolled away in every direction, the trees like the bars of a never-ending cage.

Weeks. It had been weeks since Manon Blackbeak and the Thirteen had left her in this forest, the Wing Leader ordering her to head north. To find her lost queen, now grown and mighty—and to also find Celaena Sardothien, whoever she was, so that Elide might repay the life debt she owed to Kaltain Rompier.

Even weeks later, her dreams were plagued by those final moments in Morath: the guards who had tried to drag her to be implanted with Valg offspring, the Wing Leader’s complete massacre of them, and Kaltain Rompier’s final act—carving the strange, dark stone from where it had been sewn into her arm and ordering Elide to take it to Celaena Sardothien.

Right before Kaltain turned Morath into a smoldering ruin.

Elide put a dirty, near-trembling hand to the hard lump tucked in the breast pocket of the flying leathers she still wore. She could have sworn a faint throbbing echoed into her skin, a counterbeat to her own racing heart.

Elide shuddered in the watery sunlight trickling through the green canopy. Summer lay heavy over the world, the heat now oppressive enough that water had become her most precious commodity.

It had been from the start—but now her entire day, her life, revolved around it.

Fortunately, Oakwald was rife with streams after the last of the melted mountain snows had snaked from their peaks. Unfortunately, Elide had learned the hard way about what water to drink.

Three days, she’d been near death with vomiting and fever after gulping down that stagnant pond water. Three days, she’d shivered so badly she thought her bones would crack apart. Three days, quietly weeping in pitiful despair that she’d die here, alone in this endless forest, and no one would ever know.

And through it all, that stone in her breast pocket thrummed and throbbed. In her fevered dreams, she could have sworn it whispered to her, sang lullabies in languages that she did not think human tongues could utter.

She hadn’t heard it since, but she still wondered. Wondered if most humans would have died.

Wondered whether she carried a gift or a curse northward. And if this Celaena Sardothien would know what to do with it.

Tell her that you can open any door, if you have the key, Kaltain had said. Elide often studied the iridescent black stone whenever she halted for a needed break. It certainly didn’t look like a key: rough-hewn, as if it had been cleaved from a larger chunk of stone. Perhaps Kaltain’s words were a riddle meant only for its recipient.

Elide unslung her too-light pack from her shoulders and yanked open the canvas flap. She’d run out of food a week ago and had taken to scavenging for berries. They were all foreign, but a whisper of a memory from her years with her nursemaid, Finnula, had warned her to rub them on her wrist first—to see if they raised any reaction.

Most of the time, too much of the time, they did.

But every now and then she’d stumble across a bush sagging with the right ones, and she’d gorge herself before filling her pack. Fishing inside the pink-and-blue-stained canvas interior, Elide dug out the last handful, wrapped in her spare shirt, the white fabric now a splotchy red and purple.

One handful—to last until she found her next meal.

Hunger gnawed at her, but Elide ate only half. Maybe she’d find more before she stopped for the night.

She didn’t know how to hunt—and the thought of catching another living thing, of snapping its neck or bashing in its skull with a rock … She was not yet that desperate.

Perhaps it made her not a Blackbeak after all, despite her mother’s hidden bloodline.

Elide licked her fingers clean of the berry juice, dirt and all, and hissed as she stood on stiff, sore legs. She wouldn’t last long without food but couldn’t risk venturing into a village with the money Manon had given her, or toward any of the hunters’ fires she’d spotted these past few weeks.

No—she had seen enough of the kindness and mercy of men. She would never forget how those guards had leered at her naked body, why her uncle had sold her to Duke Perrington.

Wincing, Elide swung her pack over her shoulders and carefully set off down the hill’s far slope, picking her way among the rocks and roots.

Maybe she’d made a wrong turn. How would she know when she’d crossed Terrasen’s border, anyway?

And how would she ever find her queen—her court?

Elide shoved the thoughts away, keeping to the murky shadows and avoiding the splotches of sunlight. It’d only make her thirstier, hotter.

Find water, perhaps more important than finding berries, before darkness set in.

She reached the foot of the hill, suppressing a groan at the labyrinth of wood and stone.

It seemed she now stood in a dried streambed wending between the hills. It curved sharply ahead—northward. A sigh rattled out of her. Thank Anneith. At least the Lady of Wise Things had not abandoned her yet.

She’d follow the streambed for as long as possible, staying northward, and then—

Elide didn’t know what sense, exactly, picked up on it. Not smell or sight or sound, for nothing beyond the rot of the loam and the sunlight and stones and the whispering of the high-above leaves was out of the ordinary.

But—there. Like some thread in a great tapestry had snagged, her body locked up.

The humming and rustling of the forest went quiet a heartbeat later.

Elide scanned the hills, the streambed. The roots of an oak atop the nearest hill jutted from the slope’s grassy side, providing a thatch of wood and moss over the dead stream. Perfect.

She limped for it, ruined leg barking, stones clattering and wrenching at her ankles. She could nearly touch the tips of the roots when the first hollowed-out boom echoed.

Not thunder. No, she would never forget this one particular sound—for it, too, haunted her dreams both awake and asleep.

The beating of mighty, leathery wings. Wyverns.

And perhaps more deadly: the Ironteeth witches who rode them, senses as sharp and fine-tuned as their mounts’.

Elide lunged for the overhang of thick roots as the wing beats neared, the forest silent as a graveyard. Stones and sticks ripped at her bare hands, her knees banging on the rocky dirt as she pressed herself into the hillside and peered at the canopy through the latticework of roots.

One beat—then another not even a heartbeat after. Synced enough that anyone in the forest might think it was only an echo, but Elide knew: two witches.

She’d picked up enough in her time in Morath to know the Ironteeth were under orders to keep their numbers hidden. They’d fly in perfect, mirrored formation, so listening ears might only report one wyvern.

But these two, whoever they were, were sloppy. Or as sloppy as one of the immortal, lethal witches could be. Lower-level coven members, perhaps. Out on a scouting mission.

Or hunting for someone, a small, petrified voice whispered in her head.

Elide pressed harder into the soil, roots digging into her back as she monitored the canopy.

And there. The blur of a swift-moving, massive shape gliding right above the canopy, rattling the leaves. A leathery, membranous wing, its edge tipped in a curved, poison-slick talon, flashed in the sunlight.

Rarely—so rarely—were they ever out in daylight. Whatever they hunted—it had to be important.

Elide didn’t dare breathe too loudly until those wing beats faded, sailing due north.

Toward the Ferian Gap—where Manon had mentioned the second half of the host was camped.

Elide only moved when the forest’s buzzing and chittering resumed. Staying still for so long had caused her muscles to cramp, and she groaned as she stretched out her legs, then her arms, then rolled her shoulders.

Endless—this journey was endless. She’d give anything for a safe roof over her head. And a hot meal. Maybe seeking them out, if only for a night, was worth the risk.

Picking her way along the bone-dry streambed, Elide made it two steps before that sense-that-was-not-a-sense twanged again, as if a warm, female hand had gripped her shoulder to stop.

The tangled wood murmured with life. But she could feel it—feel something out there.

Not witches or wyverns or beasts. But someone—someone was watching her.

Someone was following her.

Elide casually unsheathed the fighting knife Manon had given her upon leaving this miserable forest.

She wished the witch had taught her how to kill.

Lorcan Salvaterre had been running from those gods-damned beasts for two days now.

He didn’t blame them. The witches had been pissed when he’d snuck into their forest camp in the dead of night, slaughtered three of their sentinels without them or their mounts noticing, and dragged a fourth into the trees for questioning.

It had taken him two hours to get the Yellowlegs witch to break, hidden so deep down the throat of a cave that even her screams had been contained. Two hours, and then she was singing for him.

Twin witch armies now stood poised to take the continent: one in Morath, one in the Ferian Gap. The Yellowlegs knew nothing of what power Duke Perrington wielded—knew nothing of what Lorcan hunted: the other two Wyrdkeys, the siblings to the one he wore on a long chain around his neck. Three slivers of stone cleaved from an unholy Wyrdgate, each key capable of tremendous and terrible power. And when all three Wyrdkeys were united … they could open that gate between worlds. Destroy those worlds—or summon their armies. And far, far worse.

Lorcan had granted the witch the gift of a swift death.

Her sisters had been hunting him since.

Crouched in a thicket tucked into the side of a steep slope, Lorcan watched the girl ease from the roots. He’d been hiding here first, listening to the clamor of her clumsy approach, and had watched her stumble and limp when she finally heard what swept toward them.

She was delicately built, small enough that he might have thought her barely past her first bleed were it not for the full breasts beneath her close-fitting leathers.

Those clothes had snared his interest immediately. The Yellowlegs had been wearing similar ones—all the witches had. Yet this girl was human.

And when she turned in his direction, those dark eyes scanned the forest with an assessment that was too old, too practiced, to belong to a child. At least eighteen—maybe older. Her pale face was dirty, gaunt. She’d likely been out here for a while, struggling to find food. And the knife she palmed shook enough to suggest she likely had no idea what to do with it.

Lorcan remained hidden, watching her scan the hills, the stream, the canopy.

She knew he was out there, somehow.

Interesting. When he wanted to stay hidden, few could find him.

Every muscle in her body was tense—but she finished scanning the gully, forcing a soft breath through her pursed lips, and continued on. Away from him.

Each step was limping; she’d likely hurt herself crashing through the trees.

The length of her braid snapped against her pack, her silky hair dark like his own. Darker. Black as a starless night.

The wind shifted, blowing her scent toward him, and Lorcan breathed it in, allowing his Fae senses—the senses he’d inherited from his prick of a father—to assess, analyze, as they had done for over five centuries.

Human. Definitely human, but—

He knew that scent.

During the past few months, he’d slaughtered many, many creatures who bore its reek.

Well, wasn’t this convenient. Perhaps a gift from the gods: someone useful to interrogate. But later—once he had a chance to study her. Learn her weaknesses.

Lorcan eased from the thicket, not even a twig rustling at his passing.

The demon-possessed girl limped up the streambed, that useless knife still out, her grip on its hilt wholly ineffective. Good.

And so Lorcan began his hunt.

The patter of rain trickling through the leaves and low-lying mists of Oakwald Forest nearly drowned out the gurgle of the swollen stream cutting between the bumps and hollows.
