THE ONYX SERIES

THE ONYX SERIES

Dark Romance / Crime Thriller

3-Book Series • Alternating First Person POV • HEA in Every Book • Adults Only (18+)

Three ONYX operatives. Three women who knew too much. One secret society that has never once failed to close a directive—until now.

 

ONYX operates in the space between power and invisibility—a secret society built on conditioning, blood loyalty, and the absolute certainty that attachment is a liability. The ONYX Series follows three of its most dangerous men across three books, each sent after a woman who should have been a directive completed.

A coffee shop manager who photographed the wrong alley. An investigative journalist who mapped the wrong network. A federal prosecutor who spent twenty months building the cage they all live inside.

None of the directives were completed. The Architect is watching. And all three couples converge in the finale on the only question that matters: whether justice can survive the institution that was built to prevent it.

 

Book 1 — ONYX Obsession (Mira & Dominic)

“When a coffee shop manager accidentally photographs a secret society execution, the man who should have killed her brands her instead—and she’s about to discover that belonging to ONYX’s most feared enforcer is the most dangerous and the only safe place she’s ever been.”

Mira Santos built her entire life around three rules: stay small, stay predictable, stay invisible. She has perfected the art of going unnoticed—until the night she accidentally photographs a murder. The man holding the knife is Dominic Ashford, ONYX’s most feared enforcer, and protocol demands he eliminate the witness. Instead, he brands her with the ONYX seal and claims her as his own.

Trapped in his fortified penthouse, Mira discovers the most unsettling truth about her captor: he knows her. Three months of covert surveillance. Her coffee order, her bus route, every wall she ever built. He studied her before he claimed her—and now that she’s here, she can’t decide what frightens her more: the man who owns her, or the fact that she’s beginning to want to belong to him.

As ONYX’s inner circle closes in—demanding proof of loyalty, ordering inspections, issuing execution orders—Mira and Dominic must choose between the brotherhood that shaped him and the obsession that’s dismantling everything they thought they were.

Book 2 — ONYX Ominous (Elise & Cain)

“He was ordered to extract her secrets and eliminate her. He lied to the brotherhood, filed a false report, and destroyed twelve years of perfect service—all because she was the one variable he couldn’t make himself solve.”

Cain Volkov is ONYX’s most precise operative: no attachments, no deviations, no file that ends in anything other than Directive: Complete. When the Architect sends him after investigative journalist Elise Reyes—who has spent three months mapping ONYX’s global operations—the directive is simple: extract her source intelligence, then terminate.

Cain takes her. He conducts the interrogation. He watches her refuse to break—not from stubbornness, but from a fierce, specific intelligence that reassesses him with every answer he gives and doesn’t give. He files a false report. What follows is the most dangerous performance of his career: staging a convincing captivity for surveillance that grows more sophisticated with every hour, while in the compound’s blind spots, he and Elise are building something neither of them has language for.

When the Architect’s dossier reveals the entire assignment was an engineered loyalty test—designed to see whether an operative could be emotionally compromised—the cost of Cain’s deviation will not be borne by him alone. Not everyone who enters the Architect’s sanctuary leaves it.

Book 3 (Series Finale) — ONYX Obscura (Ivy & Lucian)

“She spent twenty months building a legal cage for ONYX. He walked into her office the night before she filed and told her they were both already inside it—and only one of them knew the way out.”

Federal prosecutor Ivy Chen has spent twenty months building an airtight RICO case against the ONYX Society—seven witnesses, fourteen traced shell corporations, a legal framework so precise it should be untouchable. Tomorrow at nine, she files the motion that brings it all down. Tonight, a man appears in her doorway.

Lucian Cross is the one name Ivy couldn’t place on her evidence wall: the heir to Cross Global Holdings, born into ONYX’s inner circle, a man who has spent his entire adult life performing loyalty he doesn’t feel. He isn’t here to threaten her. Viktor Kane authorised her assassination forty minutes ago, and Lucian is the only thing standing between Ivy and an organisation that has never lost a target.

Forced to trust the man she should be prosecuting, Ivy is pulled into a world where her evidence isn’t enough and the institutions she believed in have been corrupted from within. As Lucian’s performance of indifference cracks under the weight of what Ivy represents—the first person who ever looked at his world and called it by its right name—the question stops being whether she can prosecute him. It becomes whether either of them will survive long enough for it to matter. All three couples. One convergence point. Everything on the line.
