She's hoping she's paranoid. She's terrified she's not.

When Amelia relocated to Cambridge for love, she never imagined her new life would become a nightmare. After uprooting her beauty therapy business to be with her fiancé Noah, Amelia receives the first message—anonymous, threatening, impossible to ignore.

As more sinister messages follow, Amelia's new life begins to fall apart. It seems someone is watching her every move and now her clients are abandoning her for no reason she can see. It's as if she's done something wrong, but what?

And Noah is no help. He seems strangely distant, then conveniently vanishes to care for his sick father. Alone and terrified, Amelia suspects everyone.

Then, when a photo arrives which proves she's being stalked, Amelia realizes she's not being paranoid—the danger is very real.

Trapped in her flat, jumping at shadows, Amelia must uncover who's tormenting her—and why. Because in this game of psychological warfare, the people closest to her might be the most dangerous of all.

Trust no one. Question everything. Survive.
