The House of Borgia by Marcus van Heller

For Olympia, our Marcus takes on the notorious family Borgia, a line which included the debauched Cesare, his sister Lucrezia, and their father the Pope. In the first volume, we experience the young Lucrezia's sexual awakening, her complicity with her father's schemes to increase the family's power, and the love that drove her brother, Cesare, to murder. In the second, we turn our focus away from the family and straight to the young Cesare. A gifted politician, able general, and all-out sociopath, the man suffers with the passing of his father, loses his family posessions, and finally meets his end, all the while indulging his fabulous appetites for flesh.
