In book two of the series, The Vampire's Assistant, Darren devolped deeper into the world of vampires. A horrifying accident ends with Darren drinking the blood of his friend Sam, vowing to carry his friends spirit with him.We meet up with Darren again in Book 3 at Cirque Du Freak.

He takes Darren, and Darren's companion from Cirque Du Freak, Evra, the "snake-boy" with him.By day, Darren and Evra enjoy being around humans again and doing human activities. Darren develops a close friendship with a girl his age named Debbie. Little did he know how much danger he would put Debbie in.By night, Mr. Crepsley is taking care of his business in the city. Unfortunately when corpses drained of blood are reported on the news Darren and Evra are compelled to find out who did it. I liked this book because it kept me on my toes.
