Vivienne Calloway has exactly three rules for surviving employment at Mercer Industries.One: never be late. Two: never be unprepared. Three: never, under any circumstances, develop feelings for Kade Mercer.She broke the third rule at month two. She fixed it by month four. That's what Viv does. She identifies problems and she solves them. Quietly, efficiently, without anyone finding out. For the past seven months she has been the most composed woman in any room Kade Mercer walks into, which is impressive, because Kade Mercer walks into rooms the way natural disasters do.He's brilliant. He's insufferable. He has the body of someone who made a deal with the devil and the smile of someone who enjoyed the negotiation. He also, according to the entire internet and half the women in Manhattan, does not do relationships. He does dinners. He does weekends. He does goodbye in the morning without apology.Viv knows all of this. She filed it under reasons to stay in her lane and got on with her life.The problem is that Kade has recently noticed something strange. His most reliable employee, the woman who anticipates his schedule before he makes it, who hands him his coffee at the exact temperature he prefers, who has never once looked rattled by anything he does... has stopped looking at him.Not physically. She's still there, still professional, still terrifyingly good at her job.But something behind her eyes switched off, and for a man who has built an empire on reading people, he cannot figure out when it happened or why. And it is, inexplicably, making him insane.This is the story of a billionaire who never had to chase anything, a redhead who decided she was done wanting things she couldn't have, and the absolute disaster that happens when one of them stops pretending.
