I hope your talking about the character and not the author. Obviously, the author is not a real vampire because vampires don't exist. The character is a half-vampire though. Half-vampires are like full vampires but can go out in the day, age at a fifth instead of a tenth the human age and can not breathe out a sleeping gas or flit.
The Vampire's Assistant is the second novel in "The Saga of Darren Shan" by Darren Shan.
Darren Shan's real name is Darren O'Shaughnessy
Darren Shan himself (for the majority of versions). This is due to the fact that he himself becomes a vampire prince in this book
Darren Shan wrote Vampire Mountain.
No he is not, Larten Crepsley is a vampire in the Darren Shan saga, and the Demonata is about Demons.
