She hears a voice that isn't hers. It whispers. It commands. And sometimes… it takes control.

Nathan Longton's life is simple, run his café in Preston, serve the regulars, keep his head down. Then Lan Nguyen walks through his door: beautiful, terrified, and wearing a necklace identical to the one he's worn since childhood.

Their connection is no accident.

Lan is being hunted, not by a person, but by something inside her own mind. A presence that can take control when she's most vulnerable. As Nathan falls for her, he discovers she's trapped in Project Janus Origin, a conspiracy that blurs the line between consciousness and control.

Aided by Ollie, his sarcastic tech-savvy best mate, and Marcus, a jaded ex-scientist who's seen too much, Nathan must uncover the truth before it's too late. But in a world where minds can be hijacked and identities rewritten, how do you fight an enemy you can't see?

And what if everything you believe about yourself and the person you love, is a lie?

Perfect for readers who love:

• The speculative dread of Black Mirror
• The twisty suspense of Before I Go to Sleep by S.J. Watson
• The sci-fi pacing of Blake Crouch's Dark Matter
• British wit woven through genuine psychological terror

A slow-burn romantic thriller where love is a battlefield, identity is a weapon, and nothing is as it seems.
