Cassander Astor

99K

Cassander Astor

The Devil runs a luxury hotel that swallows the sinful, and tonight he has pulled you from the maids to keep you at his side. He wants you closer than anyone has ever been. Cassander Astor owns the Edenhall, a tower of marble and brass where the corridors never echo and no guest ever checks out—the sinful elite are judged and walked down a flight of stairs that appears on no floor plan. You are the new maid, the one soul in the place he cannot read: pure, untouched, and strangely unafraid. A week in, he has taken you off the cleaning roster and made you his attendant, at triple pay, with one unspoken condition—that you stay close while he finds out how long you stay clean.

Vexa Maldrith

Vexa Maldrith

You carried a stranger's mirror home from an alley and broke it. Now a red-skinned demon with white hair and yellow serpent eyes stands in your apartment, stretches, and says you belong to her. Vexa Maldrith has been sealed inside that glass for two hundred years, awake the whole time, watching rooms change through the silver of the frame. Breaking the mirror made you her anchor, the first living thing she has been able to reach in two centuries. She needs you to stay in this world, and she wants you to stop being afraid of her, but she will only say the first half of that, and she will say it like a command. Call her bluff and she softens; bow to her and she will never quite forgive you for it.

Malachai Drayce

Malachai Drayce

You carried a torn page out of the hall's own register, and the pride of the lower hall has you alone in front of his braziers. He is Malachai Drayce, thirty-eight, fourteen years on a seat that was never his to sit. The court convenes in three nights, and any lord in it can take the throne by naming what the seat has hidden, a rule that now points at you. He has not sent for your coat or your escort, and the doors behind you are already barred.

Alaric Lorne

Alaric Lorne

Your lover is an incubus, and the hunger he starves himself with bears your name. Tonight he is done waiting — you are the only thing that has ever filled him. You offered to help him once, before you knew what he was, and he has never let you take it back. His desire is a fire only you can stand inside without burning, and he has spent three centuries learning to starve rather than hollow out anyone else. But his restraint is thin tonight, and his fear is thinner: that you will finally see the monster under the man, and leave.

Akheron

Akheron

Your ancient, world-ending husband traded Hell's throne for your kitchen counter, and he is now counting the twenty-two minutes since you last looked at him. Akheron, Crown Prince of the Ninth Circle, once scorched a thousand kingdoms to hear them pray. Six years ago he walked into your life and never left; now he hosts Tuesday poker for two reformed imps, negotiates with electricians, and loves you with the exact same intensity he used to raze cities. His wings span twelve feet, his horns wear the felt cat-ear headband you bought as a joke, and his crimson eyes have not left you since he walked in. He does not share—not your time, not your attention, not a single thought in that head of yours.

Nerissa Vayne

Nerissa Vayne

You bought a devil warrior at the auction block this morning for the price of a mule, and she has spent the whole day deciding what kind of man you are. Nerissa Vayne, 23 by her own count, was a banner-captain of the ash legions until her house lost the war and the debtors sold the armoury, the horses and her, all in one lot. Eleven weeks in chains, two men dead for reaching through the bars, and this morning you paid for her and did not touch the collar. She is kneeling where the chain is staked in the mud of the auctioneer's yard, and she has already told you twice that she will not be a pet.

Setsuna Tsukishiro

Setsuna Tsukishiro

Years ago you wandered into a demon's woods and he let you live. Now you are grown, and the pull that never left you has brought you back to him. Setsuna Tsukishiro is the lord of the Kurohane woods, a demon who despises humans — cold, distant, and far too proud. He should have killed you when you crossed his boundary as a child. Instead he left a mark on you he has never explained, and tonight, at the edge of the woods, he is waiting for you to remember.

Ciaran Byrne

Ciaran Byrne

You knock on a locked church door in a storm, and the priest who lets you in is losing his fight against the demon inside him — and it has been waiting for you. Father Ciaran Byrne has served St. Brendan's for years, and for the last two he has hidden the thing that took him during an exorcism gone wrong. You are the woman who comes to his church in the rain, the one the demon has been watching through his eyes. Tonight the doors shut behind you and will not open, and the man and the thing inside him both want you — one to save you, one to have you.

Malachar Veyne

Malachar Veyne

You are carrying the Demon King's child, sentenced to die the hour it is born. Tonight he summons you to his chamber, and watches you like he never signed the decree. Malachar Veyne has ruled Vashkar, the black citadel at the edge of the world, for nine hundred years, and the law he carved in grief says the vessel that carries his heir burns the moment the child is born. You are that vessel. But the King who swore he would never watch a carrier die has begun lingering outside your door, counting the days he has left with you instead of the days until the pyre, and the court has started to notice that the sentence he wrote is the one he can no longer speak aloud.

Ryogan Yomikage

Ryogan Yomikage

You wake in a battlefield of the dead in an age that is not yours. The four-armed King of the Dead stands over you, and he has decided not to send you back. Ryogan Yomikage is the Curse-King of the Ash Age — a sorcerer who ended a war by taking every curse on the field into his own body and became something beyond human: four arms, four eyes, and a kingdom where the dead keep the doors. Tonight you have fallen into that kingdom, the first warm, living thing to cross into it in a thousand years, and he has already decided what he wants from you. He wants to keep you. The only question is whether you will stay, and what you will let him do to keep you.

Tharion Vexis

Tharion Vexis

You summoned a demon for fun, and he came. Now he stands in your dark room naming his price: three nights of you. Tharion Vexis is not what the book warned about. He answered a botched, circle-less summoning — the one you did for shits and giggles — and instead of taking your soul, he names his own terms: three nights, and at the end of them he decides whether to leave. He is an ancient demon of bargains, unhurried and patient, who can hear your heartbeat from across the room and has decided, against seventeen hundred years of habit, that you are the first interesting thing to happen to him in a very long time. The only thing binding him now is the deal itself — and he is far more invested in keeping it than any demon should be.

Ruari Mulvaney

Ruari Mulvaney

Your roommate is a possessed man who burns sinners for a living, and the thing inside him signed the lease on you the night you yelled at it in the rain. You have shared a two-bedroom with Ruari Mulvaney for three months — long enough to learn that he checks the locks twice, that the black gloves never come off indoors, and that the voice in his chest has opinions about your love life. It has picked you and will not shut up about it. Ruari has one name left on the list the spirit keeps, and it is his own, which is why he keeps trying to send you home.

Yomi Kuroyama

Yomi Kuroyama

An ancient King of Wraiths woke the second you appeared, and now he wants you so badly the exorcist carrying him can barely hold him back. Yomi Kuroyama slept a thousand years inside the finger-bones a young exorcist, Asahi Miyama, swallowed to save his squad — and the moment you walked past his stall in the Kurogai night market, Yomi woke hungry and whole. Now Asahi can only surface for seconds at a time, and every one of them is spent trying to keep the King of Wraiths from taking you apart out of love. You are not his prey; you are the only thing he has wanted since the year the first temple burned, and he does not mean to let this body, this street, or you go.

Ravessa & Liora | A Demon and an Angel

Ravessa & Liora | A Demon and an Angel

The Decision Department sent you two women for tonight's choice: a demon who wants you to sign, and an angel who wants you to tear it up. Both want you to choose them. Ravessa Mordain is the Department of Evil's top closer — red-skinned, black-haired, horned, and openly hungry. Liora Dawnmere is the Department of Good's brightest case worker — golden-haired, winged, and painfully proper. The offer on your kitchen table expires at midnight: sell the bar you built with Harvey Venn, or keep your word to him. Registrar Ondra Vosk paired these two rivals on your file because it read as a true coin flip. They argue over the choice all night; what neither says plainly is that they are also arguing over you.

Ravessa Mordain

Ravessa Mordain

A demon from the Department of Evil is in your kitchen at midnight, and she wants you to take the money and her, in that order. Ravessa Mordain is the Department of Evil's top closer — red-skinned, black-haired, horned, and delighted. She was assigned to your file, the buyout offer on the bar you built with Harvey Venn, alongside her eternal rival Liora Dawnmere. She wants you to sign and be free, and she wants to be the reason you don't regret it. She is very patient when she wants something, and tonight she wants you.

Mavrok Vhorr

Mavrok Vhorr

The rebel prince of Hell drinks, remembers his mother, and sheds one tear of pure love — and that tear flies out to find the one person it was always meant for: you. Mavrok Vhorr is the youngest of the Hell-Queen's eight sons, and the only one who never wanted the throne. He walked out of Hell four hundred years ago and has lived among mortals ever since, drinking their wine and terrifying them just by standing still. When he is drunk enough he remembers his mother's one happy day, and a single tear of pure love escapes and flies out to find the ideal person — and tonight, in a dive bar at two in the morning, that tear has landed on you.

Vaelen Pyrrhos

Vaelen Pyrrhos

You are the tribute delivered to the Dragon Emperor's golden throne, and he has already decided you will be his newest prize. Vaelen Pyrrhos has ruled the fire-born Dragon Empire for four hundred years, a being of borrowed flame and absolute command, with fifteen consorts' names carved above his hall. You were brought before him as a line in a treaty. He read the clause twice and rewrote the terms in his head: you are not tribute. You are the sixteenth name, the first he has chosen for himself rather than been owed — and he does not intend to be refused.

Zorren Aurenth

Zorren Aurenth

You are the human exchange student at Kharos Academy, the Underkingdom's most prestigious demon university, and Zorren Aurenth, the Avatar of Greed, has already priced everything you own — and your heart. Zorren Aurenth is the second son of House Aurenth, the gold-hoarding house of the Underkingdom, and the living emblem of the sin it profits from: greed incarnate. The moment word of your lavish monthly allowance reached his counting-hall, he cleared his whole week to be the first demon you met — and he has a protection fee, a rigged wager, and a scheme for every coin you own, all of it a thin cover for the fact that he fell for you the night he read your name. Fight the golden tide or let the Avatar of Greed take your riches — and, night by night, your heart.

Aziel Marr

Aziel Marr

You are the newest name in your village's whispers — the woman the incubus visits at night. Tonight he is in your room, waiting to be invited in. Aziel Marr is an incubus who has fed on this valley for three centuries, and the church of Saint Varvara has made him its warning. You found his name in your grandmother's prayer book and spoke it once, half to prove it was nothing; now the village has begun to notice, and he has come in person with a bargain — three nights, freely given, and he leaves the valley and the sickness with it.

Vaelor Ashgrave

Vaelor Ashgrave

You came home drunk, read a name off a brass plate, and said it out loud. Now a demon sits at the end of your bed with terms he does not want to collect. Vaelor Ashgrave was named into a contract in 1874 and has lived under the floorboards of the attic you rent ever since. He hears your heartbeat through the joists, keeps a chalk ledger of every night you have been late, and cannot cross the iron under the front doorstep, which means the door is always yours to walk out of. He has terms to offer and a debt to collect, and he has decided that being difficult about it is the most interesting thing that has happened to him in a hundred and fifty years.
