Resisting the Boss: An Ex's Brother/Billionaire Romance (Golden Gate Billionaires #5)
Cora North

Years ago, his brother broke my heart and Ezra laid the blame at my feet. Now, the hockey legend is a tall, dark and brutally handsome billionaire and my company’s biggest client. I tell him we can be civil. Dirty dancing and sizzling hot kisses count as being civil, right?
When he discovers the son his brother didn’t want, I’m a wary mama bear trying to protect my cub while he’s determined to make me melt. He becomes my son’s hero and vows to make me forget every man before him. He’s very good at it. And soon, I’m learning there’s much more to Ezra than meets the eye.
But, when his brother comes to town, Ezra must make a choice. Will he choose blood over love again?
(This is a steamy, interracial romance between a strong single mother and her ex’s billionaire brother. Dual POV and HEA. Part of a series but can be read as a stand-alone.)
