"Elphame's Choice", P.C. Cast (Young Adult-Fantasy)

I've read all but the last book in P.C. and Kristin Cast's "House of Night" series and enjoyed them.  However, I'm finding it difficult to get through "Elphame's Choice".  The world seems interesting, but I'm simply not connecting with any of the characters and finding myself bored.  I'm not sure what the issue is really.  It may be too much description and not enough dialog, or just that I'm not seeing the point of the plot, but I put this one down after reading 1/3 of the book and I really don't care how it ends.
