Anna Lillian Wade's Sweet NOTHING
In South Carolina, Thomas Granger and his forbears have been a thorn in the Wilkinsons' sides since the War for Independence. Or have the Wilkinsons been thorns in the Grangers' sides...? Nobody knows, and that suits them just fine, until Tom comes to burn down Nathan Wilkinson's wheat field, and is met by Wilkinson's headstrong eldest, Elizabeth. The blood feud spanning four generations is called to court, resulting in an ultimatum: Thomas Granger must marry Elizabeth Wilkinson, or serve time for attempted arson and an assault that never actually occurred.
Now Granger is trapped with a wife he believes seeks to ruin him, so he will ruin her first. Elizabeth is trapped with a husband who refuses to acknowledge her, so she will win his esteem. They engage in a battle of wits, where the weapons are subversion, tears, as well as many unforeseen circumstances.
