Though he is the youngest son of a royal duke, Etan is a scholar at heart, happiest in a library surrounded by his books. He contentedly juggles his work for the prince's government with his studies of the history and legends of Tournai, a subject of particular interest to him because he shares the secret magical Talent that runs in the royal bloodline. However, Etan's peaceful world turns upside down when his best friend—the man he secretly loves—unexpectedly marries someone else.
Tristan is the oldest son of a wealthy merchant, raised to shoulder responsibility for the family business one day. That day comes far sooner than anticipated, and he makes a deathbed promise to his father to marry the woman his father chose and become head of the company and family. Tristan values his friendship with Etan and has always been attracted to him, but he can't forsake his duty to his father, even if it means giving up the possibility of having Etan as a lover.
A year later, Tristan is a widower with an infant daughter and a mother who demands he marry again quickly—something Tristan resists. Circumstances throw Etan and Tristan together again, but even as they succumb to the desires they've always harbored, Etan battles his feelings, wary of being cast aside once more. When the unimaginable happens, Etan and Tristan must come together and support each other through the ordeal…and maybe beyond.
