The book "My Sister the Vampire" by Sienna Mercer?

Vampalicious is the fourth book.

The first three are "My Sister the Vampire:

...Switched"

...Fangtastic!"

...Revamped!"

When referring to books, "advanced" might be the most subjective word in Wicca. Whether or not the material in a book is advanced, depends entirely upon what the reader/student has already read/studied. I genuinely believe that most authors believe they are writing advanced books when they sit down to write. I am sure they are basing this off of what they have seen with their own students of their experiences with others. There is validity to the argument that advanced material is specialized material and most of the books on my shelf I would consider advanced are books on specific subjects. True advanced material probably only lives in two forms; in the form of specialized books on subjects that simply aren't of interest to everyone and in the notebooks and hard drives of those who train labeled as "curriculum". If I had any fantastic ideas regarding advanced books, Llewellyn would be the last place I'd take them. They can't even turn out decent beginner materials. I find it amusing that they exclude history and memoirs as I learn way more from those two types of books than any other subject. The problem is that subjects such as ritual and all the things that occur within ritual are things best learned not from a book.
