The epic series finale. A family divided. A fearful decision. A fateful choice. After the tragic loss of their daughter Genevieve, the heart wrenching issue that will determine Rosaline's future, now threatens to divide the Capulets forever. Armand's hasty vow to Friar Lorenzo on the night Rosaline was born - promising her life to the church if he could save his wife Ilaria when it appeared she would surely die - has split their marriage. In the midst of the crisis, unshakeable about the sacred vow, Armand's called back to France against a new threat of war. With a rare chance to visit their grandparents, the children must go too and Ilaria must decide whether to travel with them or stay and discover a means to undo the vow. Spurred on by the Duchess de Paris - who has her own disruptive plans for the couple - a plan's hatched for Ilaria to seek support from two of Yolanthe's most potent allies to see the vow rescinded. Yet the mercenary siren warns Ilaria, the two men in question are ruthless, the price they may seek for such help may be steep, a price Ilaria may not have the heart or stomach to pay.
