Borderline

Book One in the Fractured Mirror Series
by Susannah Turnbull

How do you escape the darkness... when it lives inside you?

Susannah has spent her life trying to outrun the chaos of her past-mental illness, trauma, and a family history soaked in silence and shame. But when a series of disturbing events shatters the fragile calm she's built, she's forced to confront the ghosts of what was, but the terrifying question of what she's becoming.

With her emotions spiraling and her relationships unraveling, Susannah begins to suspect that someone from her past is watching... waiting... and pulling her back into a dangerous game of control and psychological warfare. But is the threat real, or just a symptom of the disorder that's ruled her life for far too long?

Raw, haunting, and emotionally gripping, Borderline is a descent into the mind of a woman living with BPD (borderline personality disorder), fighting to reclaim her voice, her safety, and her identity.

Perfect for fans of Sharp Objects, The Silent Patient, and Verity-this is not just a psychological thriller. It's a reckoning.

"There's nothing more terrifying than losing yourself. Unless someone's trying to take you first."
