Hidden was a good ending to a very interesting series. The book started out fast paced and remained so most of the time. You really see what areas Jacinda has grown and how she hasn't changed in others. A new character was introduced and I found myself liking him in what little time was given to get to know him. Things are revealed and events take place that were unexpected but really added to the story. The actual ending wasn't the best I had ever read but gave a nice finality to the series. I recommened this series to those who are interested in dragons or those looking for a quick but unique read.
