Her Crazy Rich Ex High School Crush. Crazy Rich Crushes

She's on a humanitarian mission. He's the crazy rich guy funding it. Sage Erickson has finally shed her high school shyness and found something she's passionate about--helping install water pumps in South Africa. The man funding the project is none other than her old crush, and he's interested in more than her plans to educate the villages they bring water to. Which is fine with Sage. Ryker Campbell always like Sage in high school, although his pride kept him from pushing past her quiet personality.
Now she's a tenacious woman who works hard for what she believes in, and he can't help a resurgence of his old feelings. The business trip feels more and more like the vacation romance of a lifetime, but his lavish lifestyle and social connections could prove to be too much for Sage. As the two rekindle a friendship that blooms into something more, Sage worries that she's just not cut out for that kind of life.
Can they find a way to come together, or will the continents divide them forever?
