Mia Alvarez didn't come to Sterling Media to be underestimated. Three weeks in, and CEO Adrian Sterling has made it his mission to prove she doesn't belong in his boardroom. Cutting remarks. Impossible deadlines. Eyes that linger a second too long before he catches himself and looks away first.She hates him. She's almost sure of it.He runs his company like he runs everything, controlled, ruthless, untouchable. Until she walks in. Mia doesn't flinch. Doesn't fold. Pushes back in every meeting, matches him line for line, and something about that gets under his skin in a way he can't name and won't admit. He starts finding reasons to keep her late. She starts finding reasons to stay.The war escalates. A shouting match in his office that ends with them inches apart, breathing hard, neither backing down, and neither sure anymore if it's rage. A client dinner where his hand finds the small of her back and stays there too long, too deliberate to be nothing. A elevator stuck between floors, the air gone thin, his eyes dropping to her mouth before he catches himself.Every time it should end, it doesn't. A storm strands them both at the office overnight, one bottle of scotch, one torn-open collar, one line neither of them crosses but both of them want to. Mia tells herself it's a game she can win. Adrian tells himself he's still in control. Both of them are lying.The tension isn't friendly anymore. It's a slow burn with teeth, heated glances across conference tables, a hand gripping a doorframe instead of her waist, words traded like a dare. He signs her paychecks. She could end him with one email to HR. Neither of them cares anymore, and that terrifies them both.Falling for my enemy, is a steamy enemies-to-lovers romance about power, control, and the unbearable ache of wanting the one person you swore to never want, until wanting wins.
