Madman's Daughter Books in Order

In Victorian London, Juliet Moreau learns her disgraced father may still be alive and travels to his remote island with Montgomery and the mysterious Edward. What she finds is a nightmare of human-animal experiments, divided loyalties, and terrible family truths.

Back in London, Juliet tries to rebuild her life after escaping her father's island, but a killer marked by three clawlike slashes starts hunting people close to her. As her own illness worsens, she must chase a cure and face the past she thought she had buried.

Juliet flees to a strange estate on the Scottish moors with Montgomery, Lucy, Balthazar, and a dying Edward, hoping for safety. Instead she finds secret passages, old experiments, and a new test of how far she'll go to save the people she loves.
