He's Justin, a doctor who just moved to Cookoutville, moved on from his dead wife, and about to move into a swank ranch property.  She's Lorren, a children's book author not interested in love since she divorced an Awful Husband.  It's Tonight and Forever, Brenda Jackson's first book!

Generally all of the potentially troubling stuff in this book happened in the past - there's an emotionally and physically abusive ex husband, an uncool mustache, a Dead Brain Cancer Wife, that sort of thing.  Unfortunately the mustache is in the present of the book, as you can see from the otherwise fantastic cover.
