She was having his baby. But why wouldn’t she be his wife?

After several failed pregnancies, Tess Fuller’s dreams of motherhood hadn’t worked out — until one memorable night with her ex-husband resulted in pregnancy! Take-charge rancher Mitch Culhane had never stopped loving Tess. Now he has the perfect solution: marriage, take two. But Tess isn’t so sure their love story can have a happily-ever-after…unless Mitch can prove he’s changed.
