Piers Westhaven and Alice Penhallow have always been close friends, even during their marriages to other partners. Now they are both widowed, and Piers, who needs an heir, has asked his friend to help him choose a new bride. Alice has always been in love with him herself, but hiding her feelings has become second nature to her. As a boy, he dearly loved her too until his best friend announced his intention of courting and marrying her. Soon their mutual passion begins to break through the careful bonds each has imposed upon it just as Piers is being trapped into offering marriage to someone else. Will honor permit them to speak the heart's truth before it is too late? Or is it already too late for them--again?
