The Merger by Isabelle Quinn

I built my career with my own two hands. I never planned on needing anyone — let alone two men who make "no" feel like a dare. Sloane Ashford doesn't do weakness. Six years, zero favors, one flawless reputation. Then her company gets swallowed by a deal she never asked for — and so does she, the moment Grant Ellison and Rhys Calder walk into the room like they already own the air in it. Grant is control wrapped in a three-piece suit — the kind of man who doesn't ask twice. Rhys is worse: charming enough to make you forget to be careful, and hiding something far more dangerous than charm — he actually wants to know her. And the two of them? Partners in business. Partners in everything else, for longer than anyone's supposed to know. Sloane isn't interested. Sloane is a liar. Two weeks. One house. Paper-thin walls and zero exits. Every hallway a temptation, every locked door a lie she's telling herself. Grant wants to own her. Rhys wants to unravel her. And somewhere between the boardroom and the bedroom, Sloane stops fighting the pull — and starts wondering how she ever thought she could survive wanting both. Then a board member with a grudge and a file finds out. Now the only thing more dangerous than getting caught... is not caring if they do. Tropes: Forced Proximity, Billionaire Romance, Reverse Harem/Throuple, Bisexual Awakening, Workplace Forbidden, Possessive Alpha Sky-high heat. Doors close, tension doesn't. Guaranteed HEA — no cliffhanger, no regrets.
