82: Morning Glories Volume 2, by Nick Spencer (words), Joe Eisma (art), and Rodin Esquejo (covers). (2011 paperback trade, borrowed from Sarah)

In volume one, three teen boys and three teen girls enter Morning Glory Academy, a prestigious prep school with a sinister subplot and faculty.  Alternately fighting for their lives and with each other, the characters are further developed in volume 2, which consists of an "origins" story for each of the six main players.  While the stories do little to make the teens more appealing, they do deepen the evil nature of the school and lead the reader to fear the possible mission these kids could be sent on. It's dark horror dressed up in short skirts and prep ties--a delight for anyone who understands the malignancy of the teen years.
