Cassie watched the candle-shadows stutter as they descended, one by one. The dress fit perfectly, though there was a scraping along her collarbones—the brush of each movement like a shadow.
The banners above the entryway were new, she noticed; thick velvet, an obscene shade of black, the Prince’s sigil stitched with metallic thread: a crown, three points, each impaling a human face. Maybe subtlety wasn’t a virtue here.
They reached the landing overlooking the foyer. Demons everywhere, a spectrum of menace tailored in expensive cuts, thronged the lower level with bored detachment. The air stank of brimstone, sweat, and the metallic backwash of magic, as if every guest had washed up from a field hospital. A few sets of eyes lingered on her—hungry, reverent, or simply entertained.
Cassie swept the crowd, finding the difference between them and the human staff striking. Servants hunched and averted their faces. Demons watched openly. Evaluating, appraising. Some of the higher circle types even looked amused, as if the prospect of a mortal consort was a performance they’d all paid premium seats to mock.
Frey nudged her gently at the elbow. Cassie took the stairs without tripping, which was the one concession she allowed to dignity. Below, the ceremonial path was marked out with a carpet—slick as oil, flanked by humans in livery so terrified she could see their hands trembling from halfway up the banister.
Az was there, at the altar. Not a literal altar (she’d once joked about it, and he’d only smiled), but a dais of black marble, inset here and there with fossilized bones—human, she was fairly certain, given the fine joint structures and the little chips of memento mori set into the stone.
Az wore a suit conventional enough in cut, though his shirt was the same dark red as the inside of an artery. His smile was sharp and absent at once, already bored with the theater of his own ascension.
Cassie felt her own pulse trip to see Az, the way his presence sometimes made the inside of her chest feel scooped out, a cold anticipation like falling too far, too fast. She didn’t look away, not even when she picked up on the whispers threading through the mob and the growl of something in a borrowed human throat.
One step, then another. She wondered if the fabric glimmered in their inhuman eyes, whether the fragile silk would be considered armor or bait. The oddest detail was how every inch of her skin ached, not from fear—she’d shucked that years ago—but from a species of nostalgia, the memory of her mother’s hands sewing velvet lining into old coats, the muslin tape measure pulled tight across Cassie’s shoulders, recalibrated year after year as she grew.
She reached the bottom. Frey and the others broke off, dissolving into the crowd. The final approach was hers alone: a short walk down a corridor of faces, most of them beautiful and all of them dangerous. The air was so thick with sulfur and old cologne that she could taste it at the back of her teeth.
From the moment she stepped out on the marble, the crowd pressed forward, like the tide dragging her under. Demons and humans who thought they could trade on their favor. They tracked her with animal interest. Someone—one of the obsidian-lipped ones—was already whispering behind a wineglass. Cassie held her posture, eyes trained on Asmodeus, her gait steady, measured. She could feel the pulse of magic through the crowd, little electric shocks popping at the hair on her arms, threatening to peel the seams of her composure.
Az waited, hands folded in a parody of patience. He looked up at her with something between amusement and hunger. That was the thing about him: he never pretended to be anything but what he was. If he smiled at you like that, it was because he wanted you to know he meant it.
She could see her own reflection on the marbled floor as she approached, the ripple and bend of herself, how the gown gave the impression of something almost liquid, beautiful and dangerous. She straightened her spine further, like it mattered, like posture could be a shield.
A hush gathered as she mounted the first step up the dais, a pressure behind her ears. Each movement was deliberate, a ritual in its own right. She did not allow herself to look anywhere but at Az, not at the rows of predatory faces in their too-dark clothes, not at the demon who’d once propositioned her in a wine cellar, not at the mortal ambassador she recognized from an old newspaper. She kept her focus tight as a blade.
Az reached down, palm up, and the hush turned deeper. There was a tremor in the way he held his hand—a hint, maybe, that the moment was not entirely an act. The nerves, if they were there, were for her alone.
She set her fingers into his—strange, how cold they were, even in the fever-warmth of the room. A thousand stories have been told about what happened when mortals touched demon skin. She felt only the pressure, precise and not quite gentle, as if he were already preparing to pull her somewhere she couldn’t follow.
A demon officiant materialized at the altar, all bone and gold filigree, eyes like the inside of a lightning bolt. Cassie tried not to focus on his teeth, which were as fine as a shark’s, and set on a constant, reptilian grin. The air thickened, the heat of bodies and candle flame rising in a shimmer that made the world tilt on its axis.
Asmodeus did not care for pomp. The officiant wasted no time with speeches or benedictions. He garbled a string of noises—ancient, impossible to imitate, and the syllables scraped at the edge of her brain, pinging something in her skull. The world’s oldest unsolvable riddle. Cassie felt the language pass through her: not words but the memory of words, a taste under her tongue, hot and mineral as old coins. Az gave the official retort, his voice dry as kindling. The ritual was a volley, like an arms deal. Cassie’s part came next.
She recited her line, careful with the consonants. The phrase had been drilled into her until she could say it in her sleep, until it bled out in dreams. The words meant I accept, but more precisely: I surrender to the gamble of you. She tried not to let her mouth shape it as a dare, though that was what it was.
The officiant worked a pin from his sleeve, bone so pale it looked blue under the gaslights. Cassie’s heartbeat stuttered and waited for something—pain, maybe, but it was just sensation. A pressure, a sting that pulled memory forward: the smell of saline, of the old clinic near her childhood home where her mother had dragged her for immunizations and the nurses had whispered about “the strange one.” She watched as the officiant pricked Az’s palm, then hers, and pressed both together, blood mixing with a faint omnipresent sizzle. Her skin prickled at the contact, a soft burn, flesh aware of being rewritten.
They said the joining ritual would change her in ways she wouldn’t detect right away: a shift in how magic took to her, a sharpening of the senses, or sometimes just a craving for metals and the odd ability to taste lies. Cassie felt nothing at first, except the slow creep of warmth from Az’s hand, and the sour-metal taste at the back of her throat. She blinked it away.
There were more words, more of the dead language spat from the officiant’s throat like gravel, and Cassie. She could feel pressure building at the point where their hands met—like standing barefoot on a polished floor and waiting for the shock of static—until a brief ripple went through her body, toes to scalp, and left her skin faintly humming.
Az’s face didn’t change, but his grip on her hand tightened a fraction, as if he sensed the change and wanted to calibrate it, or maybe just to see how much she could take. She looked back, unblinking. The power dynamic was all for show; she knew he’d split his own throat before letting these monsters see him lose control. The thought gave her a small, illicit pleasure.
The officiant snapped something final, ominous, and the assembly responded with a single, synchronized breath.
It wasn’t applause, but the sound chilled her more than any shout, and as Az stared into her eyes as if waiting for her to suddenly behave like any ordinary human being and run, screaming in terror, from the place filled with demons, she simply asked in a quiet voice, “So which of our guests will cause trouble first?“
