Throw together a billionaire CEO who always gets his way and a feisty environmental activist set on shutting down his latest real estate development, and you know there’s going to be sparks. We all know opposites attract, but the kind of heat between these two is next level. Only an unbelievable set of circumstances could let loose a passion this hot. Like if the two of them got marooned on a breathtakingly gorgeous, uninhabited tropical island... That spark? Now it’s a blazing fire… NOTE: Unbelievable is a standalone hot adult romance. It’s the fourth story in the Beg for It series about the dominant, alpha males in the Kavanaugh family and the strong, sexy women who make them finally meet their match.
