The Magicians by Lev Grossman

Brilliant loner gets led thru a warp in a city park and into an alternate reality where he goes through rigorous testing to get accepted into Magic School.  Somehow the schoolmasters are able to alter reality so that his parents actually think he is going to a "normal" prestigious college.   Great premise - right?   All the action from there follows his predictable escapades thru 4 years of college fun and mystical schooling with all his fellow magic students. 

One horrific event during the school years kept me reading in anticipation of some good vs evil confrontation.  After graduation, they all move to NYC w/their newly minted BA in Magic, and unlimited money.  What I didn't understand is WHY were these people going to magic school?  To what end? At this point in the book, when they are young adults, they continue to appear immature, self-absorbed and aimless, and I stopped caring and stopped reading.
