Cirque Du Freak

What I have read so far is there is this kid named Darren and he goes to a freak show with his freind. Before they go home Steve stays behind and talkes to one of the freaks. Well Darren wants to know what Steve is up to and wants to help him if he gets in trouble so he stays and hides in the balcony. Darren finds out that his freind is evil and the guy he wanted to talk to was a vampire. Steve goes home and Darren goes back to his house. Darren steals the spider that was in the freak show and plays with it. Steve comes over after a week and finds out. They play with it Darren's little sister comes in and ruins the conection that controls the spider. The spider bites steve. Steve is parralized, they take him to the hospital. Darren loses spider, the spider goes back with the vampire. Darren goes and finds the vampire for a cure for steve, the vampire has a cure but Darren has to turn into a half vampire and be the vampire's slave to get it. So Darren does it to save his freind. He turns into a half vampire and goes to save his freind they have to get the antidote to him before the next day. That is all I have read so far.
