Query: A great attention grabber and keeper!

Wow! I read this book and it really kept my interest throughout. I did get a little bit lost in the subplot with Reigner history back in the 1600s that was intertwined within the book, but over all I was able to keep up! It was so very cool cause unlike in the TV show it looked like Buffy had finally met her match! I liked the book very much and now I can't wait to start the 2nd book in the GateKeeper Triology called "Ghost Roads"!
