Meant to Be by Lucy Darling

Leo Ridgeway has spent his life building an empire for the girl he’s always called his. She brings him to life with nothing more than a smile or a touch. A social butterfly, her wings are too beautiful to clip. He’s resigned himself to being her best friend and letting her grow… for now.
Rochelle Jackson has been in love with Leo her whole life. He treats her like the little sister he never had. He runs his billionaire empire with an iron fist, but when it comes to her, he only gives her sweetness. Unbeknownst to him, she wants much more than that. She has to know if he’s willing to give her every part of him.
But if Leo doesn’t stop keeping his distance, his brilliant butterfly might get away.
