Valentine's Game: A Dark Serial Killer Romance

Lyra is a detective hunted by a killer no one has ever seen. Not because he’s invisible… but because he’s her.

By day, she investigates brutal, calculated murders terrorizing the city.
By night, she becomes the same precision, the same control, the same violence — a version of herself she doesn’t remember choosing. She’s chasing a ghost. And the ghost is wearing her skin.

Then there’s Silas — a mortician with a disturbing calm around death and a mind too sharp to be innocent. He works with the victims she’s sworn to bring justice for… and something about him feels uncomfortably familiar. Like he’s standing too close to her truth.

As bodies pile up and her two identities bleed into each other, Lyra is forced into a twisted game of psychology, obsession, and control — where every clue points closer to her own reflection… and to Silas. Because he isn’t just witnessing death. He understands it.

And the most dangerous part? He might be fighting a monster of his own.

Valentine’s Game is a dark psychological romance and thriller about identity, obsession, self-destruction, and what happens when two serial killers fall into each other’s orbit while trying to outrun the ones inside themselves.

This story contains dark psychological and romantic themes. It explores serial killers hiding in plain sight, blurred morality, and the deterioration of identity through dissociation and trauma. Readers will encounter intense violence tied to murder investigations, emotionally manipulative dynamics, obsessive attachment, and morally corrupt choices. The novel also touches on the psychological aftermath of childhood abuse, forced acts done without consent, and the long-term impact of sexual trauma — presented as part of character backstory, not fetishization or glorification. Themes of control, power imbalance, trauma bonding, and the romanticization of darkness are central to the narrative.

This book is intended for mature readers who are comfortable exploring uncomfortable territory in fiction, where love is not safe, truth is not gentle, and monsters sometimes wear familiar faces.

If you like morally grey characters, obsessive romance, and twisted mind games, this story will pull you under — and won’t let you go gently.
