Elara Vance, a scrappy, off-the-books PI, survives on gut feelings and luck in London's grimy underbelly. But when a simple missing person case forces her to use a power she never knew she had, she's dragged into a hidden world of magic and conspiracy. Her accidental magic catches the eye of the city's most powerful mage, who offers her a deal: apprenticeship or prison. Plunged into a life of luxury and arcane lessons, her new world shatters when her mentor is murdered. Now, framed for the crime and inheriting a sentient, magical house she can't leave, Elara must master her volatile powers to hunt a killer in a world that wants her dead.
