The story is very well told, the characters are well developed and likeable ... Only downside: I had trouble keeping up! Does the universe is already described in other books by the same author? The geopolitical situation has often escaped and it's a shame because it is a frame of the survey! It is not always clear, between the camps, wars, and species! Some actions seem "phoned" was the explanation after the fact! The end also left me on my hunger, a protagonist who flees from Garrett with something (you never really know what) and coincidentally at the end of the investigation, kilometers traveled and Garrett's adventures, it also finds something he was looking for and known only to himself ... as the beginning of the investigation no indication anything like ... Maybe later gets to know the universe and most appreciate the investigation? (In any case, I did not find funny at all at any time)
