Although here, the author ballad us in all possible directions evoking sterile assumptions that do not lead to anything concrete in the end, it gives us food for thought for us to unravel the plot by ourselves. In previous volumes, I had taken a liking to Mac & Jericho and waited impatiently for the secrets of the dark and mysterious bookseller we are unveiled. However, I find that in this last volume, the evolution of the character and Mac revelations about the past of Jericho break the charm and charisma that they had managed to build over the course of their adventures. Once lifted the veil of mystery, both will lose a lot of interest and I'm not sure I want to know the answers to questions that are still outstanding at the end of this volume.
In this final volume, all the characters find themselves KMM and it's almost too many people at once, so far as she had accustomed us to some key characters whose personality was emphasized. I must admit that the last chapters were really surprising and surreal ending. Almost too simple compared to all the opportunities that were discussed and considered during this adventure. I thought it was a bit sloppy and quickly shipped to the end, not to mention the ideal solution seems solve all problems.
In short, from a global point of view, this series is the best I have read so far and I really enjoyed discovering it. I recommend also to all those who want to delve into a thrilling adventure and breathtaking.
