Ottilie Rushforth hides from the mighty Sorcerer’s Guild as secretary to a has-been detective. But Ottilie is also Entwined – threads of magic run beneath her skin, and the Guild would trap her in service.

Working on a plan to escape the Guild forever with her estranged fiancé, the enigmatic poet, soldier and smuggler Lewis Illing, Ottilie must track down a mysterious artefact, claim the bounty, and leave the city forever. But her sisters – Pretoria, a quick-witted sorceress and thief recently emerged from exile, and Madge, a guild mage to the core – are making offers just as unwelcome as the Guild’s. She can have a new life at the cost of everything she has ever wanted, or prestige and safety in a gilded cage.

With her life and liberty on the line, Ottilie must track down the artefact in a city being torn apart by prejudice and violence. She must choose between the two sides of herself – the fugitive or the Entwined.
