Obsidian Circle Billionaire Series

OBSIDIAN CIRCLE BILLIONAIRE SERIES

Billionaire Romance / Corporate Romantic Thriller

3-Book Connected Trilogy • Manhattan Setting • Alternating First Person • HEA

Three billionaires. Three women who refused to be pawns. One secret society built on leverage, surveillance, and the kind of buried sin that finally finds the light.

 

The Obsidian Circle rules Manhattan from behind glass walls and locked doors—a secret fellowship of billionaires who trade favours, fabricate evidence, and bury anyone who threatens the machine. But the machine is cracking. One founder’s assistant refuses to be sacrificed to save his empire. Another’s PR chief learns that loving a man with an unforgivable past means fighting the people who own his history. And the last founder—the one who built the Circle itself—discovers that the woman catering his engagement party is the only person alive who sees him clearly.

Ruthless Obsession tears a CEO’s empire to the ground and rebuilds it on partnership instead of control. Perfect Deception drags a tech billionaire’s buried takeover into courtroom daylight and forces the woman who loves him to choose truth over survival. Wicked Covenant collides a working-class caterer with the Circle’s founding king and lets love do what lawsuits couldn’t—dismantle the whole rotten covenant from the inside.

The surveillance feeds go dark. The boardroom betrayals unravel. And three couples rewrite the Circle’s covenant with something it never accounted for—consent.

 

Book 1 — Ruthless Obsession (Sloane & Knox)

“He hired her to run his empire. He never planned on the one rule he’d break to keep her.”

Knox Ashford is a ruthless CEO who built Ashford Industries by never letting anyone get close enough to touch him. Sloane Winters is the assistant who sees past the clipped negotiations and the locked office doors—street-smart, legally sharp, and the one person in the building Knox trusts with the files no one else is allowed to read.

The rule is simple: no complications. Sloane breaks it first. Knox breaks it harder. And Prescott Hale, Obsidian Circle enforcer, uses their relationship as the leash he’s been waiting to put on Knox for years.

When Prescott weaponizes surveillance photos, fabricated embezzlement records, and threats against Knox’s mother’s grave, the board suspends Knox and freezes his assets overnight. Sloane’s Queens apartment is ransacked. A federal prosecutor is paid off. Knox’s instinct is to protect Sloane by walking away—and Sloane’s answer is to refuse immunity on the courthouse steps and publicly claim him anyway.

Book 2 — Perfect Deception (Harper & Grayson)

“She needed a date for her sister’s wedding. He needed someone to bury the worst thing he’d ever done.”

Grayson Reid is the founder of Reid Technologies and the subject of an eleven-year-old story he paid millions to forget—a ruthless hostile takeover that destroyed a rival founder and built Grayson’s empire on the ashes. Harper Vale is his Head of PR, the woman who has spent three years cleaning up after Reid Tech’s image and refusing to let her boss see her as anything softer than a weapon.

When Prescott Hale threatens to leak the takeover story, Grayson needs a fake girlfriend to reframe the narrative. When Harper’s ex is serving as best man at her sister’s wedding in Rhode Island, she needs a fake date to survive it. One contract. Two people pretending they don’t already know how the other takes their coffee.

Prescott leaks the documents anyway. Harper resigns to protect Grayson. Grayson walks into a car crash that wasn’t an accident. Harper meets Vivienne Whitmore alone and is kidnapped—then handed the drive that proves the Circle itself forged the founding agreement Grayson has spent a decade atoning for. Harper bursts into a federal courtroom with the evidence that flips the entire case.

Book 3 — Wicked Covenant (Ivy & Thorne)

“He founded the Obsidian Circle. She brought it down—on her knees, by choice, in a wrecked kitchen.”

Thorne Callahan is the founding king of the Obsidian Circle, the billionaire who wrote the covenant the other members live by—and the man Prescott Hale has decided must fall. Ivy Cross is a working-class caterer with a brother in construction, a fragile new business, and no intention of ever stepping inside Thorne’s world.

Then her storefront is vandalized overnight, her equipment destroyed, and Thorne appears with a fifty-thousand-dollar contract and a proposition: pretend to be his fiancée for six weeks, neutralize the smear campaign Prescott launched against him, and walk away with enough money to save Cross Catering.

What begins as a transaction becomes a war. Prescott escalates—sabotaging a construction site that lands Ivy’s brother Julian in the hospital—forcing Thorne to confess the Circle’s full history in a conversation Ivy recorded without meaning to. When the recording goes public, Prescott is arrested, the Circle is gutted from the inside, and Thorne is left with the one question he’s never had to answer: what does a man who built an empire on leverage do when the woman he loves refuses to be leveraged?
