Airships, werebeings, and tea! Carriger wonderfully expands the world she's built through the Parasol Protectorate and Finishing School series. Rue is clearly her mother's daughter, but that pragmatism has been influenced by her adopted father and the more relaxed care that the supernatural set places on their own mortality. The result is a woman is not content being held within the bounds of propriety if she sees a valid reason to challenge its norms. However she is still young enough that she makes some rash decisions that could have quite detrimental effects. Fortunately, she has some strong friendships and a talent for leadership that engenders degrees of loyalty in her crew that range from grudging respect to firm devotion. 
 The adventures abroad that take place in this book further explore the ideas of prejudice built around supernaturals in previous works. I enjoyed seeing how other countries and regions viewed and integrated (or excluded) those who differed from the norm. Carriger makes a richer world through the interactions not only of other countries and their supernaturals, but by also highlighting the tension between England and its colonies. Showing Rue's surprise at these revelations allows the reader to see the larger picture, while showing Rue's acceptance of the concerns from those local to the colony deepens her character. 
 Prudence is a great return to this world, and I'm looking forward to the next installment.
