A History of What Comes Next

This book felt a little lukewarm for me for the majority of following Mia's adventures through Germany. I had expected a little more sci-fi but i had heard this one focuses more on the characters. I suppose this was similarly the case with the Themis Files. This whole time we're following the Kipsu vs The Tracker which was the part of the story i enjoyed the most. Who were this ‘race' of people and where did they come from. Why are they here and what are they looking for. It was great to learn about the previous ‘iterations' that came before them.
Good story.
