*As the second book in a series, this necessarily has spoilers for the first book, Soulless. Potential readers beware!*
Lady Alexia Maccon, the new muhjah and wife to werewolf Conall Maccon, has a new problem to solve when London and its environs suddenly does not have supernaturals. The ghosts disappear, and vampires and werewolves become mortal, generally in the environs of the Thames. Most disturbingly, no one knows why, though apparently their ancient lore suggests that this is not the first time something like this has happened. Lord Maccon travels to Scotland to try to work out the mystery, and Alexia soon follows when his Beta discovers that the plague - or whatever it is - appears to be traveling in the same direction as her husband.
I so enjoyed returning to the inventive world first encountered in Soulless. Alexia and Lord Maccon are as entertaining married as they were before - and their argumentative and stubborn natures stay quite true to their characters. While the first book had only a hint of flying airships and alternate technology, this one has a little bit more, and the introduction of some of the scientific alternatives in this world were fun. I'm very much looking forward to the next book which, sadly, does not come out until September.
