In 15th-century Volterra, sculptress Ravenna Maffei enters a competition hosted by a secretive, immortal family who offers an invaluable boon. Desperate to win so she can save her brother, Ravenna reveals a rare magical talent, a dangerous act in a city where magic is forbidden. The consequences make her a target, and she is kidnapped by the mysterious and powerful Luni family. 

Now a captive in the cutthroat city of Florence, Ravenna is forced into an impossible task where failure means certain death at the hands of Saturnino dei Luni, the family’s enigmatic heir. At turns seductive and then merciless, Saturnino’s capricious behavior leaves Ravenna both drawn to him and afraid one wrong move might end her life.

Meanwhile, Ravenna’s forbidden magic does not go unnoticed. The Pope, waging war against Florence, and magic itself, has his own interest in her abilities, seeing her as a potential weapon in his ruthless campaign. 

As trusting the wrong person becomes lethal, Ravenna must navigate the treacherous lines between a pope’s obsession, her love for her family, and the seductive immortal who might be the end of her.
