Living happily ever after should be easy. After all, Tristan and Isolde Gilbert, the new Duke and Duchess of Kendall, have overcome obstacles, confessed their love, married, and are eager to sail off into the sunset of their glorious future. But, of course, life rarely offers smooth sailing. After their honeymoon tour, an unexpected return to London sends the new couple reeling.

Tristan struggles to balance his new Isolde-loving self with his former role as the autocratic Duke of Kendall. Upstart relatives and scurrilous accusations complicate his efforts to find a purpose and settle into his altered standing within the ton. Worse, the still-scandalous Isolde—who never expected to be at the center of Polite Society—now finds she has to navigate meetings with the Queen, dodge vile rumors, and fend off the jealous attacks of other aristocratic ladies.

For Tristan and Isolde, falling in love was simple. But merging two disparate former lives into one proves more fraught. Can the newlyweds find a way to remain both true to themselves and one another in their new life together?
