This was a humdinger of a book!  Ritter tied all those various story lines together, the characters and (most) of the weird happenings.  I have to say, I didn't see it coming.  I really enjoyed how it all is starting to make sense.  Jackaby is beginning to be more dimensional, I never really understood his motivations before, but learning more of his backstory made his lifestyle and quirks make so much more sense.  By the end of this book, I felt there was a shift in the dynamics of the relationships between Jenny, Abigail and Jackaby.  They are a team, working toward the same ultimate goal.  This was a quick read, mainly because I wanted to know what was going to happen.  When is the next book coming out???  Not soon enough!
