Zoey was a great teenage character. The new kid in school and feeling a bit like an outcast is something I could completely relate to. Being uprooted and moving is rough for anyone, but moving AND finding out that you're not exactly human? That would be super stressful.
To add to Zoey's difficulties, the older generations of her Ice Dragon family are a bit snobbish and don't think humans are good enough for their grand-daughter (even if she is only half-dragon).
I really admired the fight that Zoey found within her self and the courage it took to stand up to her family and their traditions. I don't think her battle is over yet, but she may have won some allies to her side of the field by the end.
