What are the motifs in The Silver Kiss by Annette Curtis Klause?

A recurring idea in The Silver Kiss is that of Dislocation, or, those feelings of unreality, of being out-of-place, things being 'not right' and not working as they should. We first can see Dislocation in the book in the way that Zoe relates to her home life; the fact that it is not in actual fact a home at all, but a place where she and her father collapses after tiring days and nights at the hospital, at work or at school. This predicament is made all the worse by the loss of Zoe's mother from the home situation, until towards the middle of the book we see Zoe's home as little more then a strange and lonesome place.
