My Brother's Best Friend

Ariana didn't expect this to happen, any of it, and falling in love with her brother's best friend was only the beginning. Even knowing what kind of person he was, she couldn't help but find herself under his merciless, smoldering gaze. He was a good-looking sweet-talker, and a professional charmer. And, so, when things start to heat up, the only obstacle that she and Caleb find themselves facing is her brother.

How do they find a way to explain to him that the two people he thought he could trust the most, he may not be able to trust at all?
