In Changeless we see the humanization of the werewolves and vampires which actually brought to mind the possibility of the surprise ending (which I will not tell you about). So needless to say I wasn't surprised at the end. 
 The story seemed to follow a natural course of problem to solution with little to know unnecessary elements but at the same time; failed to keep me fully interested. 
 Conall and Alexia are still enjoyable. Though I have to admit the idea that Alexia has no soul bothers me. The idea that some people have an abundance of soul and are then more likely to be able to be turned into werewolves or vampire, or simply become ghosts is an interesting one though the idea that anyone is souless seems slightly strange. Of course, I believe this is what makes Alexia as stoic as she is. 
 While these books do seem to be set up as a form of spy mystery involving Queen Victoria's government, the vampire hives and the werewolf pack; there seems to be a slight lack of a trail to follow and instead are just simply along for the ride, as slow as that might be. 
 Like the first volume, Changeless does supply a climactic and adventurous ending in which Alexia pretty much figures out all that has been happening and why, even if you've already figured it out. 
 Overall it was a decent story though not the most exciting in any regard.
