Wally Lamb's new book, "The Hour I First Believed" has come out and of course is very good. It largely concerns the Columbine school shooting (and several other themes). Another good novel based on school shootings is "We Need To Talk About Kevin" by Lionel Shriver, who also wrote several other good novels. Seems like there hasn't been a school-shooting spree for a little while. Hope that doesn't mean one's about due.
