Primary,
This is a good example of fantasy. It makes perect since that in this world the unicorn Capricorn could talk and fly. It did not seem out of place to find the Library Fairy or the frog prince. The story worked well given the setting. The theme of this book was very clear and important. It was the theme of different things make different people happy. This was clearly presented in the search for what makes someone "happy ever after" and Claire's answer at the end. ( )
