Billionaire Country by Silver James

Rule number one: never mix business and pleasure.

These Oklahoma millionaires work hard and play harder. Country music producer Tucker Tate is laser-focused. But finding a pregnant runaway bride forces him to slow down. Zoe Parker has a voice like an angel - and nowhere to go. So when he moves her and her baby into his condo, it's just business...until it's not. Will broken rules lead to broken hearts? Or is Tucker writing his very own love song?
