Older also introduced characters after characters that interacted with Carlos without explanation. I kept thinking, wait, who was this guy again? Or who was this woman? Wait, how did Carlos know these people? Not a reading experience I enjoy when choosing an urban fantasy book :(
There were times some scenes captured my attention, that I spent time to read them carefully (one that I could remember was when Carlos was visited by a message delivery-ghost. That was cute). But in overall, the whole world-built of
inbetweeners, ghosts,
ngks (yes, WEIRD term isn't it? at first I thought it was a typo *lol*), the Underworld, and other paranormal characters just didn't reel me in.
I didn't have anything to complain about the writing though ... mainly the way the story told made me lack connection to the story, to the world, and alas, to the characters. I guess I must chalk this up as a series that most people else like but me *sigh*. Not planning to check up any sequels (if any) either.
