The Personal Trainer

(2026)
A novel by

 
 
I just wanted to get fit for my wedding day. To look my best when I marry Seb. He made me believe in love again, after the tragic death of my first husband.

So I hire Claudia, a personal trainer.

At first, she’s perfect. All golden hair, gleaming teeth and relentless positivity. Workouts, meal plans, constant messages checking in.

But then she starts turning up at my door, unscheduled; hanging around in my local park. She’s crossing boundaries.

Maybe I’m paranoid. After all, everyone says I’m moving too fast with Seb. But he’s just right for me. He lost his partner just like I did. And he’s doing his best to bring up his teenage daughter — who doesn’t seem too keen on having a stepmother. But she’ll come round, with time and patience.

One evening, I’m pulling a bottle of wine from the fridge when I spot something on the kitchen counter. A photo in a tiny, plastic frame. A headshot of a young woman. She has large, hazel eyes, shiny blonde hair.
She’s so pretty.

She looks familiar, but I can’t place her. Then it comes to me:
it’s Seb’s dead wife.

I look out the window into the darkness.

My personal trainer is parked outside my house . . . She’s looking straight at me.

Right into my eyes.
