I always hesitate to read books with fairies these days, because I'm not a fan of the whole fae thing, (I.E. someone enters a gateway, gets pulled into the realm of fae, finds out time passes differently there, then (at some far future point), that person may or may not escape the fae realm, to be dumped back into the "real world" After reading half a dozen (or so) of those kinds of stories, they no longer appeal to me, and I actively avoid such stories. Seeing this one had fairies in it, I was concerned it'd be the same type of deal, but having read the first one in the series, I was sincerely hoping that would not be the case. Thankfully, it wasn't.
The story was amusing in places,, though nothing made me laugh out loud. It wasn't a bad story, and while it was much better than I expected, I think it would benefit from (slightly) more explanations of some features of the story. I.E. The fairies are not well liked in the world, though why this is was barely hinted at, and humans were not well liked either, though this was never addressed, other than to hand wave and brush it all away, claiming humans are boring and lazy. I'd hardly think that's grounds to claim an entire race is unlikable, but whatever.
The main character is interesting, and while his circumstances appear to be unique, most of the story revolves around him working to grow in the system, even though he doesn't have the system. (yeah, I thought that odd too).
Overall though, the story isn't a bad one, and most folks will probably like it well enough.
