Reading Roger, and not so much hook-laden commercial YA fiction

I've been thinking about Roger Sutton's post the other day, about how YA hardcover is bursting at the seams with high-concept books that once upon a time were "what we called paperbacks."  I have to say that as a librarian, I am not bothered at all by the huge amounts of heavily commercial, hook-laden, slickly produced fiction.  I found that my teens read it in droves, but then also abandoned the same books a few years later as they fell out of favor for the latest commercial YA fiction.  Yes, Lauren Conrad, I'm talking about you.  In my last year there, I saw the Gossip Girl series beginning to languish on the shelf.  And yet I can't tell you how many times I had to replace worn copies of Markus Zusak's The Book Thief.  I know that ten, twenty years from now, this will endure while the others will not.  (Unless they get updates a la the Sweet Valley High, and soon, the BSC series.)

But it's fair to say that I became pretty disillusioned when I started subscribing to Publishers Marketplace in the midst of finding an agent for my first book.  Every Monday morning, skimming through the previous week's sales, my heart would sink as I read the listings.  It seemed that every single book that was sold was overly commercial and derivative, at least for debut authors.  Where are the John Greens, the Sarah Dessens, the Laurie Halse Andersons of the future?  I hope they find their way out onto the shelves, amidst the zombie-fallen angel-vampire books.
