The Emperors Childish Reign [Fred Hechinger]

In ancient Rome, Sennia Cornelia Quintilla, a noblewoman from Milan, is thrust into a dangerous marriage with Emperor Caracalla, a ruler known for his ruthless ambition and childish whims. At seventeen, Sennia's father arranges her marriage to one of the twin emperors, and despite her uncertainty, Caracalla, the older and more volatile brother, claims her as his bride.

As Caracalla's erratic behavior intensifies, his possessiveness over Sennia becomes evident. He is a man of extremes-childlike excitement over games and celebrations, yet quick to anger, using his power to control and dominate. Caught in the lavish yet perilous world of the imperial court, Sennia must navigate her new life, where loyalty is fragile, and survival often depends on outwitting those in power.

Beneath her stunning beauty and gentle demeanor, Sennia is no helpless pawn. She soon realizes that to protect herself and her family, she must play the game of empire, balancing her marriage's political significance with her growing desire for independence. As Caracalla's madness deepens, Sennia must decide whether to remain compliant or risk everything for a chance at freedom.
