I have to say, it took me a little bit to really get into this book.  I wasn't too sure at first, but I'm glad I stuck it out.  I enjoyed the pop culture references and quirky characters.  The concept was creative and I wasn't bored.  The story bogged down a bit in the middle, I could see where the plot lines would connect, but I felt it took a little too long for everyone to come together to kick some witchy butt.  A fun read, just a little uneven.
