After a medical discharge from his duties in the Napoleonic War, Thomas Quincy Fitzbatten has returned home. Disoriented, burdened by guilt for his wealth, and disillusioned with life's injustices, Thomas longs for a chance to make a difference in the world. But he keeps himself a mystery to those around him, and another motive for his charity gnaws at the back of his mind: to seek redemption from the traumatic demons of war. Then everything changes at the arrival of Ruth Dawson, the niece of Thomas's butler, a stunning woman with a secret of her own. Thomas graciously offers to assist Ruth in her predicament, but a surprise instinct prompts Thomas to handle the case a little more personally—through marriage. As their love blossoms, it appears that all will be well—until Thomas receives a mysterious letter from an old friend in trouble, compelling him to the rescue. But what will Thomas do when nothing is as it seems? And why can't Ruth shake the feeling that her destiny is intertwined with Thomas's in a way they could never have imagined?
