The Lady of the Bog by Gillian St. Kevern

An ancient queen refuses to stay in the past.

One day Florence Skelton is risking her father’s wrath by reading Jane Eyre and befriending Rosemary, the neighbourhood rebel. The next, a woman she doesn’t know is trying to drown her. To escape her would-be murderer, Florence takes a job as secretary companion to an archeologist and his beautiful, distant wife. But excavating Aylesport bog brings ancient—and deadly—secrets to the surface.

Florence can write about heroines, but navigating the bog’s treacherous waters requires courage she doesn’t possess. Her only hope of survival is Rosemary—and Rosemary doesn’t even know she’s in trouble. Can Florence find her inner heroine before she becomes part of Aylesport’s chilling history?
