Every now and again you come across a book that is both enjoyable and engaging but is also delightfully charming, and this is one of those books. 

The story is set in the Napoleonic era with the dialogue, descriptions and general style all reflecting that, which took a little getting used to, but it is this that gives it its charm. 

The relationship between Captain Laurence and Temeraire is very well portrayed and one of the highlights of the novel is watching this relationship develop. 

The concept of having an alternative history where Dragons exist and have been both domesticated and cross-bred to produce different breeds that can be used for specific aerial rolls is fascinating, and one that works wonderfully in this setting. 
There are several action scenes in this novel, with the best being towards the end, but primarily character development is the mainstay, and this is done exceptionally well. 

If you like well-written characters and Dragons then this is the book for you.
