My Best Friend’s Sister by Q.B. Tyler

For Jackson Walsh, women are as easily accessible to him as the yellow taxi-cabs outside of his New York penthouse. His days filled with growing his thriving business and his nights with countless women he’d meet while out, Jackson is only accountable for himself. Which is how he liked it. But when Jackson’s best friend asks him to watch over his little sister when she moves to the big city, he’s faced with the challenge of deciding whether the one woman he couldn’t have—the one he should stay away from was actually the woman for him.

She was his best friend’s little sister.
He was supposed to watch out for her, not sleep with her.
Not… fall for her.
