I finished Cirque Du Freak: Vampire Mountain yesterday and started reading Cirque Du Freak: Trials of Death.
In Trials of Death Darren must undergo five trials to prove himself as a vampire. If he fails, it could mean death.
Vampire Mountain was really good, but I'll wait to write a review until I finish the whole series. But I will say the series is addictive. I always get hooked right away when I begin reading one of these books and I end up reading them very quickly. They are definitely pages turners.
