The Devil's Chosen Vow

She was hired to expose him. He was born to own her. Investigative journalist Celeste Avery is handed the assignment of a lifetime: infiltrate the Obsidian Circle, an ultra-exclusive secret society, and take down its enigmatic leader, Dorian Voss. Armed with a fabricated identity as a Swiss heiress, she steps into Voss Manor expecting a ruthless criminal. She doesn't expect a man with cold, calculating grey eyes who already knows exactly who she is.
Instead of burning her cover, Dorian offers a dangerous bargain: play her part perfectly for six weeks, and he will give her the story of the century on a silver platter. The catch? She must participate in a dark, ancient initiation rite-a binding vow that ties her to him in ways she never anticipated. As the lines between her undercover role and her real desires blur, Celeste uncovers a shocking truth about her own father's hidden connection to the Circle.
With a federal operation closing in, unseen enemies plotting in the shadows, and betrayal lurking on all sides, the biggest threat isn't the story she's chasing-it's the man she's falling for. Dorian is a man built on secrets, and trusting him might cost her everything. But as the danger escalates, she realizes that the only thing more terrifying than his darkness is the way it makes her feel right at home.
