London 1888
Since she was a child, Annabel Lovelace has had to live with her uncle, the warden of Highgate Cemetery, where she discovers her strange abilty for communicating with the dead, which is perhaps due to the cardiac illness which means she lives between life and death.
Years later, a series of mysterious coincidences lead to her becoming the most influential medium in the British Empire. However, her talent causes her to discover secrets that would have been better left hidden and which shake the London aristocracy.
