Half-vampire Darren Shan is struggling with many things in his new erhm...undead life - like dealing with Mr. Larten Crepsley for one thing, the vampire who made him his assistant in exchange for saving his best friend Steve's life after Darren stole his amazing performing spider, not having any friends, and one more very important thing. Drinking human blood, which he needs to live - because animal blood just won't keep him alive for much longer.
After explaining his unhappiness to Mr. Crepsley, Larten decides to return to the Cirque with Darren, where he meets more of the freaks and gets to know them better. And, more importantly, he makes a friend in the Cirque: the snake-boy Evra Von. He also makes a curious new friend in Sam Grest; a boy who comes upon the freak show one night - none of them knowing it would have been best for him to stay away all together.
