"Why, you've never mentioned a wife" Devenish blurted then had to grace to look abashed."
"It was not more than the truth, Jack rarely spoke of Elizabeth, nor thought of her more than he had to."
Here is the Goodreads summary:
At long last, Britain is at peace, and General Jack Armstrong is coming home to the wife he barely knows. Wed for mutual convenience, their union unconsummated, the couple has exchanged only cold, dutiful letters. With no more wars to fight, Jack is ready to attempt a peace treaty of his own.
Elizabeth Armstrong is on the warpath. She never expected fidelity from the husband she knew for only a week, but his scandalous exploits have made her the object of pity for years. Now that he's back, she has no intention of sharing her bed with him—or providing him with an heir—unless he can earn her forgiveness. No matter what feelings he ignites within her…
Jack is not expecting a spirited, confident woman in place of the meek girl he left behind. As his desire intensifies, he wants much more than a marriage in name only. But winning his wife's love may be the greatest battle he's faced yet.
