Passarella is a married father of three young children, who all reside in Logan Township, New Jersey. Currently, "Jack" writes full-time when he's not working on his website design and author promotion business AuthorPromo.com. While he enjoys writing in the genres of dark fantasy, supernatural thrillers, horror, science fiction, fantasy and mystery, he has been concentrating on horror and supernatural stories in recent years.
Wither, co-authored with Joseph Gangemi, was his first published novel. Columbia Pictures purchased the film rights to Wither in a preemptive, pre-publication bid. In 2000, Wither won the Bram Stoker Award for Superior Achievement in a First Novel.
Passarella followed Wither with the media tie-ins Buffy the Vampire Slayer: Ghoul Trouble and Angel: Avatar. Next came his stand-alone sequel to Wither, Wither's Rain.
The author had two novels published in 2004, Angel: Monolith and Wither's Legacy. Next up is Kindred Spirit in June 2006.
