Dragon's Oath (House Of Night Novellas, #1) - P.C. Cast, Kristin Cast I liked this little novella. It is a great addition to the House of Night series. I would have liked if it was longer, but I can see why it was written and how it fits into the whole story of the series. This story helps you re-connect and understand Dragon and his actions in the last book. It will be interesting to see what happens next.
