The story follows Adeline Reilly, a successful author who inherits her late grandmother’s gothic mansion, Parsons Manor. What should have been a fresh start quickly turns unsettling when strange break-ins, mysterious roses, and threatening messages reveal that someone is watching her. As Adeline investigates her family’s disturbing past, she discovers that she may not be the first woman in her family to be pursued by a dangerous shadow. Meanwhile, Zade Meadows becomes increasingly obsessed with her, creating a tense and dangerous connection between them. As secrets surrounding the manor begin to surface, Adeline finds herself caught between fear, curiosity, and an attraction she cannot easily escape. The novel ends on a cliffhanger and continues in Hunting Adeline.
