Just to prove that all rules/pieces of advice are made to be broken/disobeyed, I picked up Hex Hall yesterday. It is, without a doubt, "read 200+ pages in a day and only stop because it's midnight and sleep is good before a day of reading manuscripts" friggin' awesome.
And its prologue/intro is excellent.
In fact, the whole book is highly recommended.
You know how a number of YA works have either the protag or her love interest be a new student? And then she and Mr. Love Interest get paired together as lab partners, study buddies, something like that and realize they like each other? Well, in this version, she gets paired with Mr. Lurve because he refused to beat up on her when the magic defense/PE teacher (who hates protag because of something she doesn't know about her father), and they get stuck cataloging magical items. Um--way more interesting.
