Giuseppe lives in Marius’s Venetian palazzo along with several other boys, including Armand, before Marius turns him into a vampire. Giuseppe is the smallest of all the boys. It is likely that he is killed when Santino and the Children of Darkness burn the palazzo to the ground.
Giuseppe appears in Blood and Gold (2001). For more perspectives on Giuseppe’s character, read the Alphabettery entries Children of Darkness, Marius, and Santino.
