Good day, how are you?
I'm doing well. Are you familiar with the Twilight series of books?
A little bit but I've not read any of the books. I just know about the series from what I've seen on social media or from friends.
Yeah, I always recommend the book series because the movies don't do it justice.
How many books are in the series. Like I said, I don't know too much about it other than it is a love story and it's about a vampire. 
Technically 4, but there are two companion novels and one novella that makes it part of the series.
Where does the New Moon book fall in that order? 
New Moon is directly after the first Twilight book.
Do the movies follow the book series for the most part or are there major differences?
The movies follow the books pretty closely. Any changes made in the movies are so minor that they don't make a difference. The biggest issue with the movies was the acting and how the characters acted.
Interesting. It does seem that everything I read says the books are much better than the movies.
