His Brother's Bride by Amy Vastine

She’s found the perfect man…and it’s not her fiancé

Sadie Chapman isn’t sure she loves her boyfriend, Owen, but accepts his proposal nonetheless. Love will come later, she figures. But then she meets Jonathan, Owen’s brother: a kindhearted widower with a daughter who adores Sadie. As Sadie gets to know Jonathan, she feels guilty about how comfortable she is around him. She knows Owen is a good man — but is she marrying the wrong brother?
