But once her mourning is complete, her late husband's debts drive her to seek help in Newmarket amidst the whirl of a race meet. There she encounters antiquities expert Evan Rhys, her late husband's roguish friend whom she hasn't seen since the day of his lordship's mysterious death. Now that fate has reunited them, Evan seizes the chance to win over the woman he's always loved. But once back within the old stone walls of Whelan House, long-held secrets come to light that shake up everything Kate thought she knew about her marriage. Now she wonders who she can trust with her heart, and Evan must decide between love and a truth that will separate him from all his heart desires.
