An ending that does not disappoint

Now that we know where are the silos, it is time to resume the story where we left it at the end of Volume 1.
Here we find the characters of two episodes that you sometimes intersect, sometimes avoid.
This time there is no division into several separate stories; one story to lead to the conclusion (I will not reveal, of course) that without stunning good taste leaves a good end well controlled.
A trilogy that worth to be read for fans of the genre.
