Used book – A Secret Preference, Abby Gaines, Françoise Rigal

Love sometimes lives next door... For Trey Kincaid, Sadie Beechman was never more than the girl next door. Coincidentally, she's also his sister Meg's best friend - which doesn't make her the ideal woman either. But when he returns home after years away for a barbecue where Meg is to announce her impending marriage, Trey is floored. Twice. First, because Sadie has become an extremely attractive woman. Then, because the young woman can't take her eyes off her best friend's future husband. Attracted, but also intrigued and even a little angry, Trey decides not to let go of Sadie. And not just to save his sister's marriage...
