Share a husband? You're not worthy

Princess Helena is ordered to share her wedding day, her husband, and her throne with Damon, Leah, and a child passed off as his heir. Instead of yielding, she removes her ring and activates the Black Shield Guard left by her late father. With Cassius at her side, Helena exposes treason, stolen army grain, a false heir, and the murder of the king, then rebuilds Sparta on her own terms.
