Review: "Changeless"

I was really entertained by my first steampunk read "Soulless" by Gail Carriger and so I looked forward to biting into the sequel "Changeless". Alexia Tarrabotti is now Lady Maccon after having married Lord Maccon, the formidable werewolf with a temper that is matched only by his wife's... Their marriage is a happy one and Alexia is loving the life as lady of the manor. However, suddenly her husband goes missing and a strange phenomenon is causing supernaturals to lose their abilities and turn into normal people. Something has to be done and Lord Maccon (forgetting to tell his wife... bad idea) goes to Scotland to his old pack as he feels certain that they are somehow involved.

Of course Lady Maccon does not want to be left at home in London, so she instantly books a dirigible float to Scotland. However, before she has time to throw a tantrum a veritable court of people have decided to go with her and Alexia has enough to do with keeping Ivy from falling in love, keeping her sister from teasing Ivy and keeping an eye on a suspicious French inventor who wears gentleman's attire... The scene is set for an adventure and a mystery!

However, here something goes wrong. Somehow Carriger doesn't manage to do anything with all this build-up energy and the ending was really disappointing for me... Unfortunately because I loved the first half of the book but then it just all seemed to come apart and the excitement just petered out. Too bad, it was so promising. Not sure I will read the third installment in the series "Blameless". Have any of you read it? Can you recommend it?
