I spent most of this book trying to figure out why I wasn't enjoying it. Part of the problem, I think, is that it's an utterly predictable variation on Harry Potter: a magical world exists alongside our own, the main character is a part of it, myths based in reality, bad guy wants a new world order, blah blah blah. On the other hand, the writing wasn't bad. I mean, I've read worse. Then, of course, the end happened. Even though I've read enough of the synopses of the following books to know that they're not actually you know what... yeah. Kind of a turn-off anyway.
Anyway, I think I figured out why this book didn't work for me: I can't figure out where it's supposed to be on the MICE Quotient. The world-building isn't strong enough for it to be a Milieu story. There's no central Idea. The Characters never seem to go through any great change (at least not in City of Bones, I can't speak for the series as a whole) and none of the Events are really momentous enough for it to fit in that category, either. Whereas Harry Potter started primary as a Milieu story that was touched off by an Event (Harry 'killing' Voldemort) but, by the end of the series, was a mix of Character and Idea. I think City of Bones was meant to be a mix of Character and Milieu, but the setting felt stale and none of the characters was especially compelling.
Anyone want to tell me what I seem to be missing? Or is the problem just that I'm not the target audience?
