So far this series has been good. The second book Changeless doesn't really step up the characters (until the end but more on that later) it just kind of keeps going in the same vein as Soulless. Lord and Lady Maccon are married and seem to live a happy life in England until one morning when Lord Maccon rises suddenly and in a bad temper leaving the caslte abruptly. When Alexia leaves to go about her new business as the muhjah we find that the city of London's supernaturals are not able to change (in the case of the werewolves) or find themselves without their overly-large teeth (in the case of the vampires). What caused this phenomenon no one can say, but just as suddenly as it appears it's gone again leaving everything as they were. 
 While Alexia is pondering the cause, Lord Maccon decides to leave England and head back to his former pack in Scotland, without informing the wife. When Alexia learns that the "sickness" seems to be spreading directly to Scotland where Conall is headed, she leaves in pursuit to try to give him the information. What ensues is a dirgible ride including Alexia, Ivy, Felicity, and Tunstell, plus a few surprises. 
 What happens in this book is a lot of mystery and finding out about the past. Someone wants to kill Alexia (again), but who? We get to meet the wonderful Madame Lafoux. I really enjoyed her character addition. She's still a little mysterious by the end of the book, I hope she turns out to be on the good side instead of evil. I think she would make a fine friend for Alexia. She needs someone more grounded to oppose the silly Ivy (whom I like, don't get me wrong). 
 Ok, the end. I knew that something happened. The whole time reading this I couldn't see how anything would happen, everything seemed really good. They were. Really good, that is, until right at the end. Then everything seems to go from ideal to awful in the space of a couple of pages. I eel bad for Alexia, I wonder what the next book Blameless has in store for her. (I apologize for the vagueness, but I don't want to spoil anything for people who haven't read it yet). 
 I would say definitely have the next book in hand, you don't want to finish this without being able to go on to the next right away.
