Celeste left her sister behind. Now she’s coming home…

Dr. Celeste Monroe seems to have the perfect life—a thriving psychology practice, bestselling self-help books, and the respect of her peers.

But when patient Daniel St. Clair begins stalking her and releases doctored recordings of their sessions which go viral, Celeste’s career crumbles overnight. As death threats flood in and her reputation disintegrates, she realises that what’s happening in the present may be linked to her own troubled past.

When Celeste was fourteen, her abusive mother was murdered. Celeste testified that her twin sister Leah was the killer and Leah was incarcerated in a mental institution.

Now, under intense scrutiny, Celeste’s past is coming back to haunt her. What really happened the night her mother died? Did Celeste know more than she said? Someone out there seems to think she did and now they’re threatening to destroy her.

As Celeste’s world spirals and her memory begins to fracture, she must confront a terrifying question: What if the fugue states she’s suffered since childhood have been hiding a truth far darker than she ever imagined?
