Perfect for you if...

You love psychological thrillers where the protagonist can't trust their own mind, especially if they're also unreliable narrators.
You're drawn to crime fiction set in specific time periods (here: 1969 San Francisco) where the era becomes almost another character.
You appreciate twists that recontextualise everything you've read, not just shock value for its own sake.

Maybe not for you if...

You prefer lighter reads or books that don't dwell on violence against women as a central plot point.
You need to finish a book feeling hopeful. The stakes here are genuinely dark and personal.
You're sceptical of psychic abilities and can't suspend disbelief on that concept, even in fiction.

About this book

Since childhood, Cassie has experienced terrifying nightmares. When a killer known as "The Gemini" begins targeting young women similar to her, Cassie realizes her night terrors may be real—brutal visions of actual murders. As her premonitions intensify and the Gemini's cryptic clues draw closer to her life, Cassie confronts a horrifying possibility: the monster she fears most might be someone she knows. Uncovering the truth could have devastating consequences for this young mother. Set in 1969 San Francisco, the novel weaves details from true-crime cases into a thriller that blurs the boundaries between fact and fiction, nightmare and reality, predator and prey.
