Ellie Briar is the first non-witch to be born into her family for generations. The Briar family of witches run the town of Silverton, caring for its inhabitants with their skills and magic. In the usual scheme of things, they would be burnt for their sorcery, but the church has given them dispensation in return for their protection of the borders of the Darklands, where the much-feared Leech Lords hold sway. Ellie is being trained as a steward, administering for the town, and warding off the insistent interest of the church. When her grandmother dies suddenly, Ellie's cousin Audra rises to the position of Briar Witch, propelling Ellie into her new role. As she navigates fresh challenges, an unexpected new ability to see and speak to the dead leads her to uncover sinister family secrets, stories of burnings, lost grimoires and evil spells. Reeling from one revelation to the next, she seeks answers from the long dead and is forced to decide who to trust, as a devastating plot threatens to destroy everything the Briar witches have sacrificed so much to build.
