If you've ever wished Jane Austen's heroines had access to magical contract law and a sharp fountain pen, meet Imogen Blackwell.
Imogen is a Null - born without a single thread of magic attached to her soul. In a society where magical contracts govern everything, she should be invisible. Useless. A gap in the architecture.
Instead, she's turned her absence of magic into a weapon. Working from a cramped office above a kebab shop in Clerkenwell, Imogen uses her unique Null abilities to sabotage predatory contracts that trap working-class supernatural beings in debt servitude. Her clients pay what they can, which is rarely enough. Her brownie assistant, Pip, files formal complaints about her organisational skills. And her flatmate, Clara - a survivor of a predatory magical marriage - reminds her to eat, sleep, and occasionally acknowledge that life exists beyond the next case file.
Imogen has spent five years operating beneath the notice of the authorities. Five years of quiet, illegal, necessary work. Five years since her mentor, Marcus Grimsby, was murdered the night before he was due to testify about systematic contract fraud - a case the Metropolitan Occult Police was ordered to bury.
That anonymity ends with a knock on her door and a summons she can't refuse.
Lord Nathaniel Frost, Chief Inspector of the Metropolitan Occult Police, Homicide Division, needs a Scribe's expertise. Wealthy young husbands from pureblood families are being murdered - their marriage bonds severed by a method that shouldn't exist. The High Council is panicking. The Scribe profession is under threat. And Imogen's name has turned up in a dead man's papers.
Frost is everything Imogen's world taught her to distrust: aristocratic, powerful, a man who enforces the very system she's spent her career subverting. He moves through Mayfair townhouses and Council chambers with the ease of inherited authority, his charcoal suits immaculate, his manner precisely calibrated to maintain hierarchy. He is, in every way that matters, a Darcy for supernatural London - contained, duty-bound, and far more complicated beneath the surface than his position suggests.
But Frost is also a man carrying secrets of his own. A family duty that keeps him chained to an ancestral estate. A case he was ordered to close five years ago - a case connected to Grimsby's murder. And a growing conviction that the institutions he serves are failing the people they were built to protect.
Their investigation draws them into a conspiracy that reaches from the hidden workshops of the Warrens to the glittering ballrooms of supernatural high society. A serial killer is harvesting magical power from the marriages of the elite, running a supernatural Ponzi scheme funded by soul-equity liquidation and disguised as philanthropic reform. The trail leads through predatory contracts, brownie intelligence networks, and a gala at the legendary Obsidian Hall - where three hundred aristocrats gather to witness a proposal that is actually a death sentence.
The romance unfolds the way Austen's best love stories do - not through grand declarations, but through the accumulating evidence of character revealed under pressure. Expect the slow-burn tension of professional respect deepening into trust. Gloved hands that almost touch. First names offered like state secrets. Loaded silences in institutional corridors. And the particular agony of two people who understand, with painful clarity, that the investigation comes first - and who keep finding reasons to stand slightly closer than protocol requires.
Welcome to the Society of Polite Magic. Mind your manners. Read the fine print. And never, ever sign anything without a Scribe present.
