The Night My Best Friend Stayed Over (My Best Friend's Betrayal #8)

I’m a food scientist. I analyze composition for a living — what’s in something, what shouldn’t be, what’s been added without you noticing.

I moved to Atlanta six months ago for my husband’s job. Left everyone I knew eight hundred miles behind. No friends within driving distance. No one to call on a Wednesday evening.

Then I met her. Warm, funny, immediate. She showed up at my door with wine and a casserole and became my best friend in the space of three weeks. She was everything I needed — a lifeline in a city where I knew no one.

She stayed over on a Thursday night. Just a girls’ night. Wine, a movie, the spare bedroom. Nothing unusual.

Except my husband came home early. And the next morning, something in the house smelled wrong. Not the cumin in my spice rack. Something else. Something chemical and floral that didn’t belong to me.

I’m trained to detect what doesn’t belong. To identify contamination at parts per million. And now I’m applying that training to my own home, my own bed, my own marriage.

But she’s not just a woman who slept with my husband. She’s done this before — in other cities, to other isolated wives, with the same playbook. And the women who’ve survived her are watching. Because this is Book 8. And the reckoning has arrived.

The Night My Best Friend Stayed Over is the final book in the My Best Friend’s Betrayal series. Books 5-8 are a connected arc — the same predator, the same women, and the confrontation that ends it all.
