The Vampire's Assistant (Cirque Du Freak)

Darren joins the vampire, Mr Crepsley, as his assistant and they return to the Cirque Du Freak. There, Darren makes friends with the snake-boy, Evra Von (who knows what Darren is) and a local boy, Sam, and RV, an eco-warrior and animal lover (who do not). Darren begins to enjoy his life among the Cirque performers as the youngest half-vampire in existence, but he defiantly refuses to drink human blood - the whole idea sickens him - and he tries desperately to cling on to the part of him which is human.
