Looking for romance books with rich women falling for average men.

I read mostly romance but it doesn't seem like rich millionaire women who fall for poor or average men below their status in society is a thing in fiction. Billionaires, royalty, or guys in powerful careers who fall for average women seem to be the norm. Does anyone know of any stories featuring the woman being the boss in the relationship? I'm not talking about Dominatrix-type stuff, just role reversal in romance.
