It’s the height of the Italian Renaissance. In the golden city of Florence, art is equal to holiness—and angels walk among us, bestowing their talents…for a price.

Seventeen-year-old artist Virgil is in trouble. To support his family, he’s bargained most of his life away to an angel—only to discover that his missing brother is in danger, and nothing but magic can rescue him. Now, with just a few months left to live, Virgil is desperate enough to try the one thing he swore he would never, ever do—team up with the infuriating, annoyingly talented, and most notorious playboy in all of Florence, the charming Leonardo da Vinci.

As the two journey through Florence’s gilded streets, luxurious cathedrals, and glorious Medici palaces, they unearth dark truths beneath the city’s facade.

Those in power will do anything to keep their deadly secrets safe, but with his feelings for Leonardo giving him new life, Virgil is determined to expose their lies before he runs out of time.

Even if it might cost him his soul.
