The Sweetest September (Harlequin Super Romance Series #1938)

A mistake that's meant to be… 

All John Beauchamp wants is a simple life. He's happy running his Louisiana sugar cane plantation and doesn't want more than that. Then Shelby Mackey breezes in, announcing that she's pregnant. Their one crazy night of passion has changed everything. 

Except Shelby insists John doesn't have to be involved—she'll raise the baby herself. But John can't let her go that easily. Even without the baby, Shelby is a breath of fresh air. Her call-it-as-she-sees-it attitude intrigues and attracts him. So when Shelby agrees to stay temporarily, John's determined to make that stay permanent—and as sweet as can be.
