But -- I did read this one. The person who lent it to me said the narrator's voice was perfectly convincing, so I looked at the first few pages, and yes, it is convincing. The novel is about two middle-school boys, both at the bottom of their school's pecking order, who eventually plan a Columbine-style massacre. The narrator is, so to speak, more the Dylan Klebold of the pair -- socially maladroit, but someone who ordinarily would most likely eventually find himself, outgrow his awkwardness, and pull through OK. His friend, edgy and sociopathic, is never going to be OK, on some level realizes this, and has nothing to lose.
I won't spoil the ending -- a friend may lend you the book one day -- but I will say my friend was absolutely right; the narrator's voice is so pitch-perfect a recreation of junior high alienation that I often put the book down, launched on a flashback of my own very worst moments at Franklin Junior High, 1966-69. All I can say is: Holden lives.
