House of Marionne

House of Marionne is the first book in a fantasy series set in a hidden magical society called the Order, which operates in secret alongside the modern world. Magic flows through the blood of chosen families who organize themselves into four Houses, each governed by a Headmistress and structured like an elite boarding school. Members complete three Rites to officially join the Order through a formal debut called Cotillion. A forbidden strand of magic called toushana, a destructive, ice-cold force that causes anything it touches to decay, is punishable by death. The Order's enforcers, assassins known as Draguns, hunt and kill anyone who carries it.

The novel opens from the perspective of Yagrin, a young Dragun who kills a woman on orders from his Headmistress. Yagrin is deeply conflicted and has secretly faked his own Dragun induction. The narrative shifts to Quell Marionne, a 17-year-old who has spent her life on the run with her mother, Rhea, moving through 14 schools across nine cities to hide the toushana in Quell's veins. While picking up wages at the French Market in New Orleans, Quell witnesses Draguns murder a captive and is briefly detained by a masked man wearing a cracked-column sigil. Her toushana flares and destroys part of a stone wall, and Rhea insists they flee immediately.

When a Dragun disguised as a classmate tracks Quell to their motel, Rhea gives her a jeweled dagger, a transport compact filled with glowing powder, and a key chain that allows mother and daughter to signal each other. Rhea sends Quell away alone, promising to follow. The designated safe house is destroyed, and the Dragun nearly catches Quell before she uses the last transport powder to reach Chateau Soleil, the estate of her grandmother, Headmistress Darragh Marionne.

At the gates, Jordan Wexton, a Dragun Ward stationed at the estate as a trainee enforcer, attacks Quell before she identifies herself. Inside, Abby, a healer training in the Shifter specialty, a form of magic that transfigures matter, mends her wounds and explains that diadems, metallic crownlike growths visible only to those with magic, mark every magic user. Grandmom appears youthful despite her age and urges Quell to enter induction. Quell initially plans to leave when her mother arrives but attends a Transfiguration session and successfully performs non-destructive magic for the first time. She learns that binding with one type of magic dulls access to others, meaning that binding with proper magic at Cotillion could bury her toushana forever. Electrified by this possibility, Quell signs the inductee roster.

Life at the Chateau proves difficult. Jordan, assigned as her mentor, watches Quell relentlessly. She befriends Abby and Shelby Duncan, a Secundus (second-rank) student, while struggling to control her toushana in etiquette sessions and coursework. When Quell's diadem emerges overnight, it is black, a marker of toushana rather than the gold or silver of proper magic. Panicking, she strikes a deal with Octos, a Trader (a freelance dealer in magical goods) and House Ambrose dropout she met at the Tavern, an underground hangout. In exchange for her mother's dagger and a stolen Location Enhancer, a tool used to track magical targets, Octos transfigures the diadem to rose gold, a disguise that holds only as long as Quell keeps her toushana under control.

Her struggle intensifies during honing, the process of folding enhancer stones into her dagger for Second Rite. A Purifier Enhancer, a stone designed to ward off magical impurities, violently triggers her toushana whenever she holds it alongside the dagger. Jordan folds the stone into her blade himself and guides her through additional enhancers. She fails her first honing exam, and Grandmom secures one additional chance, threatening expulsion. Jordan transforms the conservatory into a magical beach matching Quell's lifelong dream so she can practice in calm. She passes the retaken exam spectacularly before all four Headmistresses, including Beaulah Perl, Jordan's aunt, whose cracked-column brooch Quell recognizes as the sigil of the Dragun who hunted her.

Grandmom grooms Quell as her heir, steering her toward Cultivator, a specialty that strengthens others' magic by touch, and introducing her to the other Houses' heirs at a Summer Blooms Tea. When Quell touches the bare arm of Nore Ambrose, she finds it bone-chillingly cold: the sign of toushana. Quell begins secretly visiting a dead section of forest to feed her toushana, deliberately using her destructive magic on trees to keep it sated after observing Jordan vent his summoned dark magic in a similar fashion. She writes to Nore repeatedly but receives only silence.

Quell and Jordan's relationship deepens through shared evenings and a first kiss at the Tidwell Ball in New York City. Jordan reveals that Draguns summon a controlled form of toushana from outside themselves, using it briefly before chasing it off. When two House of Perl students are found dead and Nore goes missing, Jordan places a tracer inside Quell, a piece of his magical energy that lets him sense her distress, before leaving to investigate.

Nore is announced as found alive, but Quell discovers locked shelves in Grandmom's bedroom filled with death registries spanning generations. The most recent entries include the two Perl students and Nore, whose entry confirms she had toushana and is dead. When Quell confronts Jordan, her toushana flares and he feels the unnatural cold, realizing she has been hiding it. He brings her to Grandmom, who confirms the forbidden magic through a blood test and reveals that she herself developed toushana on the night of her own Cotillion, hiding it ever since. Grandmom modified Third Rite so that anyone who binds at Chateau Soleil is secretly tethered to the House in servitude. She admits to killing the Perl students because they discovered this secret, then locks Quell in a spare room and demands she bind with proper magic or face execution.

Alone, Quell reaches a turning point: Her toushana has never lied to her, has consistently protected her, and is the only thing she truly controls. She decides to bind with her toushana instead of her proper magic, choosing freedom over another cage. She feigns compliance and secretly arranges a rendezvous with Abby after the ceremony.

At Cotillion, Jordan escorts Quell. During their First Dance, she takes the lead, signaling defiance. Backstage, Jordan admits he loves her and warns that duty would compel him to hunt her. She kisses him goodbye, then onstage unleashes her toushana to shatter the invisible tethering barrier, publicly exposing Grandmom's secret. Offstage, she plunges her dagger into her chest, binding with her toushana. Her dress shifts from blush to black, her diadem reverts to its true form, and she flees. Headmistress Beaulah intercepts her to offer refuge rather than punishment.

In the forest, Quell witnesses Felix, a Dragun from House of Perl, murder Shelby, who had conspired to replace Quell as heir. She meets Abby; Abby's boyfriend, Mynick, from House of Ambrose; and Octos at the rendezvous. They divide tasks: Abby and Mynick will search for Quell's mother, while Octos will train Quell. Looking back, Quell sees Chateau Soleil as it truly is, decrepit and crumbling, its magical veneer stripped away by her toushana.

A final chapter reveals that Yagrin has tracked the Sphere, the vessel containing all magic, to a mountaintop using a Location Enhancer and a reverse summoning elixir, a potion that traces magical signatures. He attacks the Sphere to avenge the Order's murder of Red, his girlfriend and an Unmarked person, someone without magic. Jordan arrives via a childhood magical tether connecting them and begs Yagrin to stop. Yagrin cracks the Sphere further but cannot break it, then shifts into his other persona: Octos. He has been the Trader throughout the entire story. He forged letters from Quell's mother, transfigured her diadem, and now plans to train her. The novel closes with the Sphere fractured but intact, Quell on the run with her toushana fully bound, and the Order's power structures cracking alongside their most sacred artifact.
