Jo Graham’s fascinating series recounting the life of Giulia Farnese, mistress of the notorious Borgia pope Alexander VI, continues with The Blood of the Bull. In Jo’s version of the story, Giulia is not merely a formidably learned advisor and patroness, she is a Dove, a seer developing her power through the dangerous new scholarship flourishing in the Renaissance. In the first two novels, Giulia stood at Rodrigo Borgia’s side, first to defeat plots against the then-cardinal’s life, and then to work with his family and allies to see him elevated to the papacy as Alexander VI. In the classical language of her era, she has chosen to be Persephone to the Borgia Hades, and as his acknowledged mistress, she has risen to the heights of power and influence.

It is now 1494, and storms loom on the horizon. A French army is marching toward the Kingdom of Naples, and all that stands in their way are the fragile Papal States.  If Rodrigo won’t surrender to the French, he has enemies who are eager to see him deposed – even if that means the French sack the city of Rome and kill thousands.

Yet an even darker threat is growing. In Florence Friar Savonarola’s movement is burning books and priceless works of art, determined to purify society and destroy the Renaissance itself. Giulia’s own abilities as a seer make her a target for Savonarola’s purifying zeal. The repentant concubine of a Borgia Pope would be the perfect tool to bring Pope Alexander VI to his knees.

In a web of deceit, assassination and betrayal, Giulia must face her most dangerous enemies without Rodrigo by her side. To prevail, she will need all her wits and courage to descend into the darkness of the underworld – and return if she can.

I’m delighted to share the stunning cover of The Blood of the Bull, created by the supremely talented Alexael, who did the equally splendid covers for A Blackened Mirror and The Borgia Dove. Alexael captures Giulia’s strength and vulnerability as she faces her greatest challenge yet, and gives a glimpse of the indomitable will that will either save or doom her. I also have to point out a few of the details, from the Borgia bull and the Farnese lily flanking the title to the crossed keys and crossed swords in the lunette behind Giulia’s head. It’s a pleasure to work with an artist who understands and uses the period’s iconography.

The Blood of the Bull will be released July 7, 2025. Check back for a giveaway and for further information on this exciting new novel!
