From birth, Cesare Borgia is surrounded by shadows. Damned by his own father and driven by the demons, his quest for power threatens to set the world of Renaissance Italy ablaze. This book takes the reader on a journey into the world of the Borgias, a world of unspeakable conspiracies and forbidden desires.

Faced with the dark truth surrounding his accursed birth, Cesare is driven over the edge of sanity, straight into the arms of Hell. Will his other worldly transformation tear from him the last shred of humanity and leave only the ruthless conqueror in its stead?

Renaissance Italy is rushing headlong toward war, but Cardinal Cesare Borgia has other things on his mind. Burdened with the tempestuous affections of his younger sister Lucrezia and the ever-increasing tension between himself and his reluctant right-hand assassin Chiaro, he's caught by surprise in the clutches of a woman.

When a pair of seductive eyes comes between Cesare and his brother Juan, the escalating tension between the two finally explodes in a frenzy of rage. Will Juan's blade find Cesare's blood glistening on its edge, or will Cesare's ever-quickening descent into madness lead to a much more gruesome end for his dear brother?

In the aftermath of murder and betrayal, the darkness within Cesare only continues to thrive. Chiaro suffers seeing his master and friend lose himself to his curse but finds comfort and warmth within the confines of a monastery.

As demons within Cesare grow stronger, so do the feelings between Lucrezia and Chiaro, who saves her from the evil advances of Il Perotto. Horrified by the growing bond between them, Cesare informs Lucrezia that she is to be married off at once. Defying Cesare, Chiaro settles the question of Il Perotto once and for all, and flees with Lucrezia.

Cesare is well on his way to fulfilling his dark destiny, with the help of his newfound power. Seizing control of the French army, he begins the murderous rampage that would be his downfall - but for his loyal friend Chiaro, who can hear the last remaining vestige of Cesare's soul crying out for release.
