I am not a book series kind of person. I like books to be nicely wrapped up at the end. Maybe that's odd, I don't know – it's me. So, I can only do a top 5.
1. the Dexter books
2. the Jurrasic Park series
3. the Anne Rice Vampire Chronicles – probably only because it's one of the few series I've read.
4. the Sweet Valley High series – c'mon that was amazing
5. Nancy Drew because I AM NANCY DREW.
