Bad Best Friend - Billionaire's Club, #14

Six overprotective older brothers. One hopelessly single younger sister. She loved her brothers, but, hell, they were ANNOYING. And good at scaring off every single man she'd ever dated. Cora just wanted the happy ending, the man would love her and her flaws. The one who wouldn't be scared off by her six scary brothers. But that man didn't appear to exist. Until one day there was a knock at the door.
And Rafe showed up, moved in, and-Proved that her brothers' best friend was the only man on the planet who wasn't scared.
