A third volume I swallowed as fast as the first although the action starts slow to get under way. I found that it was pulling a little on the length wondering where the author had lead. If some questions are answered, some gray areas persist (among others, I still have not picked up how events could lead to the manufacture of a miracle cure ...). As for the end, the author does reserve the possibility of a sequel? In short, yes, I liked this last volume, but it is not up to the other for my taste.
