Adrienne Plover is an ymbryne appearing in The Desolations of Devil's Acre, after her loop was assaulted by Caul.
The Desolations of Devil's Acre[]
Miss Plover ran a loop in Squatney, East London, which was one of the few that survived the London hollow raids. This was why it was the first target for Caul's renewed loop attacks.
After Caul ripped down her house, Miss Plover was able to get most of her young wards out safely, except for Sheena and Ruzzie, which she was distraught about. Afterwards, she flew to Devil's Acre, where she reported on what happened for Amos Dextaire's radio news broadcast. She had to stop after breaking down crying.
Though it's not specifically noted what happened to her, it is assumed she would create a new loop with her surviving wards.
