More Than a Billionaire by Krista Noorman

Her brother’s best friend is the guy of her dreams. If only he’d see her as more than a friend.

Skylar Schultz has spent half her life loving Franky Middlebury, the only guy who’s ever seen her as more than heiress to the Schultz Chocolate fortune, but she’s always been firmly positioned in the friend zone. As much as she cherishes their friendship, she wishes he would see her as so much more than his best friend’s little sister.
Things aren’t going well for Franky. His girlfriend left him, he’s unhappy as a partner in his father’s law firm, and he feels stuck in a life he didn’t really want. The one bright spot is Skylar. She’s there for him in a way nobody else is, filling his stressful days with laughter and offering unending encouragement.
As their friendship progresses, they begin to rely on each other as they’re faced with family drama and career changes. All the while, Skylar hopes their newfound closeness will blossom into more, but Franky is more complicated than the happy-go-lucky guy he appears to be. And when someone new walks into his life, will she be the fresh start he’s been longing for or will he finally see the one who’s been there for him the whole time?
