i like the part where paks relation/feeling to her old friends change as she herself change and matures . Then she realize how oblivious she is to everyone around her ( the reader as well, since we follow her point of view).
the capt stefen incident in book 1 ending or 2 starting ? .. i sorta know who's the culprit is before the revelation in later books

stuff like that shows the authors attention to details and every detail counts !
