Age is Just a Number

The night was a blank page. Then a single look from across a crowded room reached all the way into Ari and moved something-and she spent the whole cab ride home telling herself she'd never see him again.
She was wrong about that. She was wrong about a lot of things.
She's twenty-five, hiding whose daughter she is, determined to earn everything on her own. He's forty-eight, the most relaxed man in a building full of people who want something from him. Neither of them is supposed to want this. Neither of them can stop.
What they don't know is the one name that connects them-the name that can turn a quiet, careful love story into something that detonates a forty-year friendship.
A slow-burn, age-gap romance set inside a music-and-fashion empire, about a line drawn at midnight that neither of them quite manages to hold-and wanting the thing you swore you'd walk the long way around. Explicit, with a hard-won happy ending, for the people brave enough to want out loud.
