I read Looking For Alaska a few weeks ago and while it wasn't that bad, it had "HELLO I AM A DEBUT YOUNG ADULT NOVEL" written alll over it.
It had the necessary introspective narrator with a quirky interest, a kindred spirit with whom said narrator waxes philosophical and their first conversation sets up said quirky interest as a metaphor for the plot, ending with a monologue explaining the metaphor for anyone too dumb to not catch it in the first five pages.
(basically if Phinny from A Separate Peace was a manic-depressive pixie dream girl)
but maybe I've just gotten too cynical for YA novels
