Falling for Her Billionaire Best Friend by Maria Hoagland

Billionaire next-door neighbors Mary Alice Howe and Ryland Neilson have mothers who are are lifelong best friends. But throwing their children together for everything from Camelot Cruise birthday parties to cotillion classes has ensured a close friendship, not the hoped-for romance.
Excited to become the newest CEO of his father’s company, Ryland takes a risk that just might ruin the company. Taking a chance on a relationship with his best friend Mary Alice, however, seems even more foolish. Sure, he’s had a slight crush on her for a while now, but they can’t get their timing right to give a romantic relationship a shot.
Already unsure what she wants to do with her career and her relationship with pro soccer player Camden Sharpe, adding new and thrilling feelings for her best friend causes Mary Alice’s world to spin upside-down. One thing she does know is that she wants a fairy-tale romance. Ryland may look like the part of the handsome prince—tall, dark, and gorgeous—but can a woman be swept off her feet by someone she shared orthodontist appointments with?
When a personal ad brings the two together, they realize that maybe they don’t actually know everything about each other. Discovering new sides to their personalities adds a surprising layer to their relationship. Yet when old expectations arise, they’ll have to decide if it’s better to stay in the safety of the friend-zone or jump down the rabbit hole of the unknown and risk everything for love.
