Thriller & Mystery Reads on Kindle Unlimited

Kindle Unlimited is where the twist costs nothing and the sleep costs everything.
This fortnight it's thriller and mystery — the ones the group chat won't shut up about, the ones you start at 9pm and finish at 2am, furious and delighted.
Five this round. All free on KU. All worth the lost sleep.

The Housemaid — Freida McFadden
A maid, a too-perfect house, and a wife you absolutely cannot trust. The one everyone means when they say “that twist.”
Psychological thriller, now a film, and still the gateway drug.

The Good Sister — Sally Hepworth
Two sisters, one buried secret, and a loyalty that curdles into something lethal. (An Aussie author, too.)
Domestic suspense, done devastatingly well.

No One Knew — Kendra Elliot
A woman who's outrun her past for years. The detective who starts pulling the thread.
Romantic suspense that does not loosen its grip.

The Divorce — Freida McFadden
She's leaving him. He has other plans. A marriage thriller that turns the screws a little tighter every chapter.
Mean, fast, and impossible to put down.

Lights Out — Navessa Allen
The couple who slays together. Viral, very dark, and very spicy — for when you want the twist and the heat both.
Not for the faint-hearted. You've been warned.

A small note: Kindle Unlimited rotates its shelves, so titles drift in and out. If one's moved on by the time it catches your eye, the link still leads the way.

Wherever this fortnight's reading takes you — the locked room, the unreliable narrator, the 2am “just one more chapter” — the Kindle comes too.
Our Kindle cases are made for exactly that kind of reading.

Back in a fortnight with the next five.
