Is the book " World of Warcraft The Shattering " part of a series?

A new World of Warcraft book came out about a mounth or so ago called "The shattering" by christie Golden and it said it was the prelude to the new game cataclysm. I dont really get into that kind of thing or have read those books in the past so i dont really know about them, but what my question is, is this book part of a series or is it just an independant book not coiated with a series or anything?
