Ever wondered what happens when a sadist meets her match? Sadist by Chaos Davie answers that with a spicy, blood-soaked sapphic dark romance that keeps its sense of humor. As the opener to the Triarchy Collection, it earns a spot on any list of the best dark sapphic romance books.

What Is Sadist About?

Sadist follows Theo, a disgraced contract killer who ends up with a hostage she never planned for. When tech mogul William Vanguard tries to extort a powerful underground vigilante network, his only daughter, Octavia, lands in the crosshairs — and in Theo’s hands.

But Octavia is hiding a secret, and secrets have a habit of slipping loose at the worst possible moment. As the two women’s worlds collide, the question isn’t just who Octavia really is, but who walks away alive. Told in dual POV and shot through with dark humor, it’s a story of a sadist meeting someone who might just be her equal — and it lands on a hard-won happy ending.

What Makes This Dark Sapphic Romance Work

Chaos Davie balances menace and wit with real confidence. What stands out:

A “sadist meets her match” hook. Octavia’s hidden edge flips the captor-captive dynamic into something far more interesting than a one-sided power play.
Dual POV. Getting inside both Theo and Octavia deepens the cat-and-mouse tension.
A twist of humor. The dark comedy keeps the murder and rage from tipping into pure bleakness.
Feminine rage as fuel. The book leans into anger as a driving force, giving both women teeth.
A dark romance that delivers an HEA. Despite the body count, it commits to a satisfying resolution.

Book Synopsis

Theo is a contract killer whose reputation has taken a hit, and taking a hostage was never part of the plan. But when William Vanguard tries to squeeze a dangerous vigilante network, his daughter Octavia becomes leverage — and Theo’s problem. What should be a straightforward complication turns into something else entirely once Octavia’s own secret starts to surface.

As captor and captive circle each other, it becomes clear that Octavia is no helpless victim, and Theo may have finally met someone who can match her. The dual-POV narrative plays their collision for tension, heat, and dark humor in equal measure, building toward a confrontation with real stakes — and, ultimately, toward a happy ending that feels earned rather than tidy.

My Review

Chaos Davie (also known for the equally sharp Savage) has a real gift for dark romance that doesn’t take itself too seriously, and Sadist is a great showcase. The “sadist meets her match” premise is the smart move — because Octavia isn’t a passive hostage, the captor-captive setup becomes a genuine two-way power struggle, which is so much more fun than the alternative. Theo is deliciously lethal, and the dual POV lets you feel both women recalibrating as they realize what they’re dealing with.

The tone is what sets it apart. There’s murder and feminine rage aplenty, but the twist of humor keeps it buoyant — it’s dark without being grim, and that balance is harder to pull off than it looks. The heat is high and well-integrated into the enemies-to-lovers tension, and at 300 pages it moves briskly. It also delivers an HEA, so the darkness has a satisfying destination.

Honest notes: it’s still a dark romance with a captor-captive core and a full content-warning list, so it won’t suit readers who want that dynamic off the page. And the humor-meets-murder tone is a specific flavor — a few readers may find the tonal shifts jarring. But if you like your dark sapphic romance smart, spicy, and a little wicked, this popular Triarchy opener is an easy recommendation.
