All I'm going to say about this series is that it was something new, before my journey into Christopher Pike. This was like Goosebumps 2.0 and it left a mark on me. While the descriptions got better and the stories were more engaging, I found the dialogue to be a little wooden at times. Not to say that I didn't have favorites. But, like the Goosebumps series, I slowly began to realize that the books were getting...well...goofier.
The ones that did it right, out of the 35 book series, were Who's Been Sleeping In My Grave, The Ooze, and How to be a Vampire
The one thing that I took away from these books was to always make the dialogue interesting.
Also, the covers were pretty out there. Look at the the one above. It's almost like the vampire is a puppeteer or someone who goes (forgive the pun) Bat-s#*t Crazy about reading.
