Sweet billionaire romance novels typically feature an insanely rich, successful, handsome hero who falls in love with a down-to-earth, relatable heroine. Despite the hero's wealth, the books are typically light-hearted and fun, with little to no explicit sexual content, which makes them a little different from famous books in the billionaire genre like 50 Shades of Gray.
Though they leave out the sex, sweet billionaire romance novels have much in common with their steamier counterparts, including a lead male with a larger-than-life personality and a reputation for being a powerful businessman and an irresistible heartthrob. The heroine sees past the walls he built around himself and fallsin love with him for who he is. The novels often feature high-stakes plots, with the hero and heroine facing many obstacles, including disapproving family members, jealous ex-lovers, and business rivals.
