To all of London society, Lord and Lady Tremaine had the ideal arrangement: a marriage based on civility, courteousness, and freedom—by all accounts, a perfect marriage. The reason? For the last ten years, husband and wife have resided on separate continents.But once upon a time, things were quite different for the Tremaines... When Gigi Rowland first laid eyes on Camden Saybrook, the attraction was immediate and overwhelming. But what began in a spark of passion ended in betrayal the morning after their wedding—and now Gigi wants to be free to marry again. When Camden returns from America with an outrageous demand in exchange for her freedom, Gigi's decision will have consequences she never imagined, as secrets are exposed, desire is rekindled—and one of London's most admired couples must either fall in love all over again...or let each other go forever.
