Theirs to Claim by Isabelle Quinn

Cordelia Ashworth has one rule: never mix business with pleasure. As the newly hired estate manager for the reclusive Ashcombe brothers, she's supposed to keep their crumbling family vineyard running — not learn what it feels like to be looked at like she's the only thing in the room. But Edmund Ashcombe doesn't ask. He commands, low and unhurried, like he already knows she'll obey before she does. And something in Cordelia, something she's kept locked down for years, finally stops fighting him on it. Then Rupert turns those same hungry eyes on her, and instead of jealousy, she finds herself wanting both of them — at once, without apology. The brothers don't share. They've never had to want the same thing before. Edmund rules by control — cool, deliberate, a man who takes his time and never loses himself, until Cordelia makes him forget every rule he's built his life around. Rupert is heat without a leash — reckless, insatiable, the kind of want that doesn't ask permission twice. Between them, Cordelia becomes the one thing neither brother can master alone, and the only thing they've ever agreed to share. But Thornecliffe runs on secrets, and every night the three of them spend tangled together is a risk none of them can afford. The vineyard is one bad harvest from ruin, a rival buyer is circling, and their late father's will hides a clause that could tear the estate — and the obsession growing between all three of them — apart before it's had the chance to become something real. Cordelia has ninety days to save the business she was hired to fix. She has no plan at all for how to stop wanting them both, or how to survive being wanted back. Some arrangements aren't meant to last. This one refuses to end quietly — and neither will they.
