This third book in the series is another solid installment in the series. This is really a fun romp of a boarding school spy thriller set in a steampunk version of England. What more do you need to know? Perhaps you need to know that the protagonist is strong willed and willing to break conventions when it suits her. That she will never be a pretty flower in a gentleman's bouquet and that really unsettles the people around her. Perhaps you need to know that there is one of the best teen romances I have read in a long time in there among the action - never slowing it down for one second. Now go read it!
