In a vastly different and darker Philadelphia of 1844, steam power has been repressed, war threatens from deep, dark waters, and one young lady of high social standing is expecting a surprise at her seventeenth birthday party–but certainly not the one she gets!Jordan Astraea, who has lived out all of her life in Philadelphia’s most exclusive neighborhood, is preparing to celebrate her birthday with friends, family and all the extravagance they might muster. The young man who is most often her dashing companion, Rowen Burchette, has told her a surprise awaits her and her best friend, Catrina Hollindale, wouldn’t miss this night for all the world!But storm clouds are gathering and threatening to do far more than dampen her party plans because someone in the Astraea household has committed the greatest of social sins by Harboring a Weather Witch.
