Love is the most dangerous magic.

As a sculptress, Ravenna Maffei has always shaped beauty from stone, but she has a terrible secret. Desperate to save her brother, she enters a competition hosted by Florence's most feared immortal family, revealing a dark power in a city where magic is forbidden.

Now a captive in the cutthroat city, Ravenna is forced into a dangerous task where failure means certain death at the hands of Saturnino dei Luni, the immortal family's mesmerizing but merciless heir. But as he draws her closer, Ravenna realizes the true threat lies beyond Florence's walls.

The Pope's war against magic is closing in, and Ravenna is no longer just a prisoner but a prize to be claimed. As trusting the wrong person becomes lethal, Ravenna must survive the treacherous line between the pope's obsession and the seductive immortal who might be the end of her ? or surrender her power to a city on the brink of war.
