The Oh Billionaires! series by Jolie Day features alpha billionaire CEOs working at the same company in New York City. Published between 2019 and 2020, the five books deliver steamy romantic comedy with tropes that range from secret babies to fake girlfriends to auction romances. Each novel is a standalone with no cliffhangers, though characters from other entries occasionally make brief appearances.
His Fake Girlfriend kicks off the series with a fake-dating setup that earned Jolie Day a USA Today bestseller tag. Billionaire Boss: Secret Baby and Billionaire Baby Daddy play on the secret pregnancy angle, while Sold: Highest Bidder brings a darker edge with its auction premise and a mystery surrounding the heroine’s brother. The series shares some crossover with the Outlaw biker romance books, with familiar faces appearing across both worlds.
